Electronic cigarette (EC) users often create their own refill fluids by blending bottled nicotine/propylene glycol/glycerol mixtures with Do-it-Yourself (DIY) flavourings.1 Although a complete refill fluid usually contains nicotine, the flavouring solutions themselves are an additive and are presumed to be free of nicotine, which is a known addictive chemical and toxicant.2 To determine if DIY flavourings are nicotine free, we evaluated 30 products from one vendor, using high performance liquid chromatography (HPLC) (figure 1B–D), and confirmed the presence of nicotine via gas chromatography and mass spectrometry (GC-MS) (figure 1E, F). HPLC analysis was performed as previously described in detail.3 Nicotine was extracted from DIY flavorings4 and GC-MS analysis of the extracts was performed using a Hewlett-Packard 5890 Series II gas chromatograph equipped with a Restek Rtx-1MS, 30 m, 0.25 mm column and a Hewlett-Packard 5971A mass selective detector.

Background

Although the overall impact of Electronic Nicotine Delivery Systems (ENDS) on public health is unclear, awareness, use, and marketing of the products have increased markedly in recent years. Identifying the increasing number of ‘vape stores’ that specialise in selling ENDS can be challenging given the lack of regulatory policies and licensing. This study assesses the utility of online search methods in identifying ENDS vape stores.

Methods

We conducted online searches in Google Maps, Yelp, and YellowPages to identify listings of ENDS vape stores in Florida, and used a crowdsourcing platform to call and verify stores that primarily sold ENDS to consumers. We compared store listings generated from the online search and crowdsourcing methodology to list licensed tobacco and ENDS retailers from the Florida Department of Business and Professional Regulation.

Results

The combined results from all three online sources yielded a total of 403 ENDS vape stores. Nearly 32.5% of these stores were on the state tobacco licensure list, while 67.5% were not. Accuracy of online results was highest for Yelp (77.6%), followed by YellowPages (77.1%) and Google (53.0%).

Conclusions

Using the online search methodology we identified more ENDS vape stores than were on the state tobacco licensure list. This approach may be a promising strategy to identify and track the growth of ENDS vape stores over time, especially in states without a systematic licensing requirement for such stores.

Text-only warnings were perceived as less effective than all of the pictorial styles (p<0.001 for all). Graphic warnings were given higher effectiveness ratings than symbolic or testimonial warnings (p<0.001). No differences were observed in levels of agreement with negative attitudes and beliefs across message themes, after respondents had viewed warnings.

Conclusions

Pictorial warnings are more effective than text-only messages. Pictorial warnings depicting graphic health effects may have the greatest impact, consistent with research from high-income countries on cigarette warnings.

Evidence from the USA and elsewhere has linked smoking depictions in movies with youth smoking initiation. Prior research has not focused on depictions in films produced in the Middle East, however.

Objective

We reviewed the 10 most commercially successful Iranian films released each year over three decades (1982–2011) to determine trends in depictions of tobacco use over time.

Methods

Each movie was reviewed in its entirety, and depictions of smoking were recorded and classified as direct (characters holding or using tobacco products) and indirect (tobacco products appearing in the frame, but not being used). Time trends in average duration of direct, indirect and total smoking depictions were analysed using linear regression and Cohen's coefficient.

Results

The mean duration of tobacco depictions in the most commercially successful Iranian films fluctuated yearly over the 3 decades, but with an overall significant upward trend (p<0.005). The proportion of movies depicting tobacco consumption during the three decades was 36% (1982–1991), 60% (1992–2001) and 74% (2002–2011), respectively. The average proportion of total movie time for these depictions (0.75%, 1.41%, 2.08%) increased significantly (p<0.005) over the 3 decades as did the average duration of smoking depictions,(39.1, 67 and 99.3 s, respectively, p<0.005).

Conclusions

The significant increase in the proportion of movies depicting tobacco consumption and in the duration of smoking depictions over the past 30 years underscores the need for increased regulation of the Iranian film industry to minimise this important source of influence on tobacco initiation in young people.

The tobacco industry claims that increases in tobacco tax will not discourage people from smoking because smokers will simply substitute taxed cigarettes with smuggled untaxed cigarettes.1 The experience in Hong Kong suggests that smuggled cigarettes are eating into some of the taxed cigarette market share, as the industry suggests. However, despite this increase in the illicit market, higher tobacco tax does effectively reduce total tobacco consumption.

Hong Kong is an ideal place to test the impact of increasing cigarette duties on smuggling as it does not have any domestic tobacco manufacturing and there are few exemptions for duty on cigarettes.2 Hence, nearly all cigarettes legally available in the market are taxed when they are imported. The analysis below is based on data obtained between 2009 and 2010, and examines the impact of the first increase in tobacco tax in Hong Kong in 8 years.3

Understanding product development and marketing strategies of transnational tobacco companies (TTCs) has been of vital importance in developing an effective tobacco control policy. However, comparatively little is known of the waterpipe tobacco industry, which TTCs have recently entered. This study aimed to gain an understanding of waterpipe tobacco products and marketing strategies by visiting a waterpipe trade exhibition.

Methods

In April 2014, the first author attended an international waterpipe trade exhibition, recording descriptions of products and collecting all available marketing items. We described the purpose and function of all products, and performed a thematic analysis of messages in marketing material.

Results

We classified waterpipe products into four categories and noted product variation within categories. Electronic waterpipe products (which mimic electronic cigarettes) rarely appeared on waterpipe tobacco marketing material, but were displayed just as widely. Claims of reduced harm, safety and quality were paramount on marketing materials, regardless of whether they were promoting consumption products (tobacco, tobacco substitutes), electronic waterpipes or accessories.

Conclusions

Waterpipe products are diverse in nature and are marketed as healthy and safe products. Furthermore, the development of electronic waterpipe products appears to be closely connected with the electronic cigarette industry, rather than the waterpipe tobacco manufacturers. Tobacco control policy must evolve to take account of the vast and expanding array of waterpipe products, and potentially also charcoal products developed for waterpipe smokers. We recommend that tobacco substitutes be classified as tobacco products. Continued surveillance of the waterpipe industry is warranted.

In 2010, the New Zealand (NZ) government introduced an annual 10% tobacco excise tax increase. We examined retailers' adherence to recommended retail prices (RRP), and whether the RRP included the full tax increase.

Methods

We collected price data on three British American Tobacco (BAT) factory-made cigarette brands, (premium, mainstream, and budget), and one roll-your-own tobacco brand before and after the 2014 tax increase from a sample of tobacco retailers. We examined price increases in each tobacco brand and compared these with the RRP. The extent to which the excise tax increases had been included in the RRP since 2010 was estimated using data sourced from the Ministry of Health and NZ Customs.

Findings

The median increase in price from before to after the tax change was only 3% for the budget brand (461 retailers). This contrasted with the median of 8% for the premium brand (448 retailers), and 11% for both mainstream and roll-your-own brands (471 and 464 retailers, respectively). While many retail outlets made changes according to the RRP set by BAT, several did not comply. Our analyses suggest BAT may be undershifting excise tax on the budget brand, and overshifting tax on brands in other price partitions.

Conclusions

Tobacco companies do not appear to be increasing the RRPs of budget brands in line with tobacco excise tax increases. The increasing price differential between budget brands, and mainstream and premium brands may undermine cessation and impede realisation of New Zealand's Smokefree 2025 goal.

Policy misalignment across different sectors of government serves as one of the pivotal barriers to WHO Framework Convention on Tobacco Control (FCTC) implementation. This paper examines the logic used by government officials to justify investment incentives to increase tobacco processing and manufacturing in the context of FCTC implementation in Zambia.

Methods

We conducted qualitative semistructured interviews with key informants from government, civil society and intergovernmental economic organisations (n=23). We supplemented the interview data with an analysis of public documents pertaining to the policy of economic development in Zambia.

Results

We found gross misalignments between the policies of the economic sector and efforts to implement the provisions of the FCTC. Our interviews uncovered the rationale used by officials in the economic sector to justify providing economic incentives to bolster tobacco processing and manufacturing in Zambia: (1) tobacco is not consumed by Zambians/tobacco is an export commodity, (2) economic benefits outweigh health costs and (3) tobacco consumption is a personal choice.

Conclusions

Much of the struggle Zambia has experienced in implementing the FCTC can be attributed to misalignments between the economic and health sectors. Zambia's development agenda seeks to bolster agricultural processing and manufacturing. Tobacco control proponents must recognise and work within this context in order to foster productive strategies with those working on tobacco supply issues. These findings are broadly applicable to the global context. It is important that the Ministry of Health monitors the tobacco policy of and engages with these sectors to find ways of harmonising FCTC implementation.

Through the Twitter Firehose, we obtained access to all public tweets posted between 6 December 2012 and 20 June 2013 that contained a keyword suggesting a tobacco-related product or behaviour (eg, cigarette, vaping) in addition to a keyword suggesting a price promotion (eg, coupon, discount). From this data set of 155 249 tweets, we constructed a stratified sampling frame based on the price-related keywords and randomly sampled 5000 tweets (3.2%). Tweets were coded for product type and promotion type. Non-English tweets and tweets unrelated to a tobacco or cessation price promotion were excluded, leaving an analytic sample of 2847 tweets.

Results

The majority of tweets (97.0%) mentioned tobacco products while 3% mentioned tobacco cessation products. E-cigarettes were the most frequently mentioned product (90.1%), followed by cigarettes (5.4%). The most common type of price promotion mentioned across all products was a discount. About a third of all e-cigarette-related tweets included a discount code. Banned or restricted price promotions comprised about 3% of cigarette-related tweets.

Conclusions

This study demonstrates that the vast majority of tweets offering price promotions focus on e-cigarettes. Future studies should examine the extent to which Twitter users, particularly youth, notice or engage with these price promotion tweets.

It has been argued that as smoking prevalence declines in countries, the smokers that remain include higher proportions of those who are unwilling or unable to quit (a process known as ‘hardening’). Smokeless tobacco and e-cigarettes have been promoted as a strategy to deal with such smokers. If hardening is occurring, there would be a positive association between smoking prevalence and quitting, with less quitting at lower prevalence. There would also be a neutral or negative association between prevalence and the number of cigarettes smoked.

Methods

We examined US state-level associations using the Tobacco Use Supplement (1992/1993–2010/2011) and Eurobarometer surveys for 31 European countries (2006–2009–2012) using regressions of quit attempts, quit ratios, and number of cigarettes smoked on smoking prevalence over time.

Results

For each 1% drop in smoking prevalence, quit attempts increase by 0.55%±.07 (p<0.001) in the USA and remain stable in Europe (p=0.53), US quit ratios increase by 1.13%±0.06 (p<0.001), and consumption drops by 0.32 cig/day±0.02 (p<0.001) in the USA and 0.22 cig/day±0.05 (p<0.001) in Europe. These associations remain stable over time (p>0.24), with significantly lower consumption at any given prevalence level as time passed in the USA (–0.15 (cig/day)/year±0.06, p<0.05).

Conclusions

Consistent with prior research using different data and methods, these population-level results reject the hypothesis of hardening as smoking prevalence drops, instead supporting softening of the smoking population as prevalence declines.

E-cigarette use has rapidly increased. Recent studies define prevalence using a variety of measures; competing definitions challenge cross-study comparison. We sought to understand patterns of use by investigating the number of days out of the past 30 days when adults had used e-cigarettes.

Design

We used the 2014 Minnesota Adult Tobacco Survey, a random digit dial population survey (n=9304 adults). Questions included ever using e-cigarettes, number of days used in the past 30 days and reasons for use. Smoking status was determined by combustible cigarette use. Histograms of e-cigarette use were visually inspected for current, former and never smokers with any 30-day e-cigarette use. Different definitions of current use were compared.

Results

Use ≤5 days in the past 30 days demarcated a cluster of infrequent users at the low end of the distribution. Among those with use in the past 30 days, infrequent users were the majorities of current (59%) and never smokers (89.5%), but fewer than half of former smokers (43.2%). Infrequent users were more likely to cite curiosity and less likely to cite quitting/cutting down other tobacco use as reasons for use.

Conclusions

Defining adult prevalence as any use in the past 30 days may include experimenters unlikely to continue use, and is of questionable utility for population surveillance of public health trends over time. Defining prevalence as >5 days excludes those infrequent users.

Bans on flavoured cigarettes have been enacted in the USA,1 the EU2 and elsewhere. However, little is known about industry and consumer counter reactions. Djarum, which controls 97% of flavoured cigarette sales in the USA, immediately released ‘cigars’ resembling their banned counterparts and continued to manufacturer flavoured cigarettes.3 This study describes: (A) online consumer interest4 in, and (B) promotion and availability of Djarum cigarettes, and their cigar replacements, before and after the USA banned flavoured cigarettes in 2009.

Methods

Google searches originating in the USA including ‘Djarum’ in combination with ‘cigarette/s’ versus ‘Djarum’ in combination with ‘cigar/s’ (eg, ‘Djarum cigarettes’ would be pooled in the cigarette trend) were monitored (google.com/trends), then regressed on time (eg, 2008–2014).

The top 50 Google search results between 29 August 2013 and 28 November 2014 for ‘Djarum cigars’ and ‘Djarum cigarettes’ were classified as websites that described Djarum...]]>

The WHO established the MPOWER policy package to boost the implementation of the WHO Framework Convention for Tobacco Control (WHO FCTC) in 2008 and to provide practical guidance on policies effective at reducing smoking rates. An easily applied Abridged SimSmoke was developed to help countries gauge the effect of these policies using data from the WHO MPOWER/WHO Report (MPOWER Report) and is applied to four Eastern Mediterranean countries.

Methods

The number of smokers in a country is calculated using the country's smoking prevalence and population. Policy effect sizes, based on previously validated SimSmoke models, are applied to the smoker populations to determine the reduction in the number of smokers resulting from implementing policies. The number of smoking-attributable deaths is derived based on findings that half of those smokers alive today will die from smoking.

The Abridged SimSmoke model has been used to show the number of deaths from smoking and how MPOWER policies can be used to reach the WHO non-communicable deaths voluntary target for cigarette use reduction in four countries.

Tobacco companies have made extensive efforts to build alliances against comprehensive smoke-free legislation. This article analyses the interaction between actors who opposed the development of the European Council Recommendation on smoke-free environments.

Methods

Drawing on data from 200 policy documents and 32 semistructured interviews and using qualitative textual analysis and organisational network analysis, opponents’ positions on, and responses to, the policy initiative, strategies to oppose the policy, and efforts to build alliances were investigated.

Results

The non-binding nature of the policy, scientific evidence and clear political will to adopt EU-wide measures combined to limit the intensity of commercial sector opposition to the comprehensive EU smoke-free policy. Most tobacco companies, led by the Confederation of European Community Cigarette Manufacturers (CECCM), voiced reservations against the proposal, criticised the policy process and fought flanking measures on product regulation. However, some companies focused on instigating harm reduction debates. These divergent approaches and the reluctance of other commercial actors to demonstrate solidarity with the tobacco sector prevented the establishment of a cohesive commercial sector alliance.

Conclusions

The comparatively limited opposition to EU smoke-free policy contrasts with previous accounts of tobacco industry resistance to tobacco control. While context-specific factors can partially explain these differences, the paper indicates that the sector's diminished credibility and lack of unity hampered political engagement and alliance building. Industry efforts to emphasise the benefits of smokeless tobacco during smoke-free policy debates highlight the potential of harm reduction as a gateway for tobacco companies to re-enter the political arena.

Raising the tobacco sales age to 21 has gained support as a promising strategy to reduce youth cigarette access, but there is little direct evidence of its impact on adolescent smoking. Using regional youth survey data, we compared youth smoking trends in Needham, Massachusetts—which raised the minimum purchase age in 2005—with those of 16 surrounding communities.

Methods

The MetroWest Adolescent Health Survey is a biennial census survey of high school youth in communities west of Boston; over 16 000 students participated at each of four time points from 2006 to 2012. Using these pooled cross-section data, we used generalised estimating equation models to compare trends in current cigarette smoking and cigarette purchases in Needham relative to 16 comparison communities without similar ordinances. To determine whether trends were specific to tobacco, we also examined trends in youth alcohol use over the same time period.

Results

From 2006 to 2010, the decrease in 30-day smoking in Needham (from 13% to 7%) was significantly greater than in the comparison communities (from 15% to 12%; p<.001). This larger decline was consistent for both genders, Caucasian and non-Caucasian youth, and grades 10, 11 and 12. Cigarette purchases among current smokers also declined significantly more in Needham than in the comparison communities during this time. In contrast, there were no comparable differences for current alcohol use.

Conclusions

Our results suggest that raising the minimum sales age to 21 for tobacco contributes to a greater decline in youth smoking relative to communities that did not pass this ordinance. These findings support local community-level action to raise the tobacco sales age to 21.

Nicotine is known as the drug that is responsible for the addicted behaviour of tobacco users, but it has poor reinforcing effects when administered alone. Tobacco product design features enhance abuse liability by (A) optimising the dynamic delivery of nicotine to central nervous system receptors, and affecting smokers’ withdrawal symptoms, mood and behaviour; and (B) effecting conditioned learning, through sensory cues, including aroma, touch and visual stimulation, to create perceptions of pending nicotine reward. This study examines the use of additives called ‘pyrazines’, which may enhance abuse potential, their introduction in ‘lights’ and subsequently in the highly market successful Marlboro Lights (Gold) cigarettes and eventually many major brands.

Methods

We conducted internal tobacco industry research using online databases in conjunction with published scientific literature research, based on an iterative feedback process.

Results

Tobacco manufacturers developed the use of a range of compounds, including pyrazines, in order to enhance ‘light’ cigarette products’ acceptance and sales. Pyrazines with chemosensory and pharmacological effects were incorporated in the first ‘full-flavour, low-tar’ product achieving high market success. Such additives may enhance dependence by helping to optimise nicotine delivery and dosing and through cueing and learned behaviour.

Conclusions

Cigarette additives and ingredients with chemosensory effects that promote addiction by acting synergistically with nicotine, increasing product appeal, easing smoking initiation, discouraging cessation or promoting relapse should be regulated by the US Food and Drug Administration. Current models of tobacco abuse liability could be revised to include more explicit roles with regard to non-nicotine constituents that enhance abuse potential.

To explore among a diverse range of smokers and recent ex-smokers, particularly those from disadvantaged groups, how nicotine-containing products, particularly electronic cigarettes (e-cigarettes), are understood and experienced.

Methods

Qualitative study of 64 smokers and ex-smokers in Central Scotland. Twelve focus groups and 11 individual interviews were carried out with a range of purposively selected groups.

Results

Nicotine replacement therapies and e-cigarettes were regarded as being very different products. Nicotine replacement therapies were viewed as medical products for smokers who want to quit, while e-cigarettes emerged as an ambiguous product whose meanings are still being negotiated. Participants’ attitudes and intentions about smoking and quitting were especially important in shaping their understanding of these products. Four main interpretations of e-cigarettes were identified: a more satisfying replacement for smoking, an ambiguous but potentially useful device, a less desirable cigarette and a threat to smoking cessation. The acceptability of continued nicotine addiction and the similarity of e-cigarettes to conventional cigarettes were central themes on which participants held conflicting views. There was considerable uncertainty among participants around the constituents and safety of e-cigarettes.

Conclusions

Different groups of smokers bring diverse expectations, requirements and concerns to their evaluations and therefore to the potential use of nicotine-containing products. The ambiguity around e-cigarettes in public health debates and medical practice is reflected in the positions and concerns of smokers. There is a need for both clear, up-to-date trustworthy information about their benefits and risks, and stronger regulation.

Despite a declining prevalence in many countries, smoking rates remain consistently high among young adults. Targeting contextual influences on smoking, such as the availability of tobacco retailers, is one promising avenue of intervention. Most studies have focused on residential or school neighbourhoods, without accounting for other settings where individuals spend time, that is, their activity space. We investigated the association between tobacco retailer availability in the residential neighbourhood and in the activity space, and smoking status.

Methods

Cross-sectional baseline data from 1994 young adults (aged 18–25) participating in the Interdisciplinary Study of Inequalities in Smoking (Montreal, Canada, 2011–2012) were analysed. Residential and activity locations served to derive two measures of tobacco retailer availability: counts within 500 m buffers and proximity to the nearest retailer. Prevalence ratios for the association between each tobacco retailer measure and smoking status were estimated using log-binomial regression.

Results

Participants encountering high numbers of tobacco retailers in their residential neighbourhood, and both medium and high retailer counts in their activity space, were more likely to smoke compared to those exposed to fewer retailers. While residential proximity was not associated with smoking, we found 36% and 42% higher smoking prevalence among participants conducting activities within medium and high proximity to tobacco retailers compared to those conducting activities further from such outlets.

Conclusions

This study adds to the sparse literature on contextual correlates of smoking among young adults, and illustrates the added value of considering individuals’ activity space in contextual studies of smoking.

To examine the association between recalled exposure to point-of-sale (POS) cigarette marketing (ie, pack displays, advertisements and promotions such as discounts) and reported cravings to smoke while visiting a store.

Methods

Data were collected using a telephone survey of a cross-sectional sample of 999 adult smokers in Omaha, Nebraska. Recalled exposure to POS cigarette marketing was measured by asking respondents about noticing (a) pack displays, (b) advertisements and (c) promotions in store in their neighbourhood. A 3-item scale indicating the frequency of experiencing cravings to smoke in locations where cigarettes are sold was created by asking respondents: (1) "feel a craving for a cigarette?" (2) "feel like nothing would be better than smoking a cigarette?" and (3) "feel like all you want is a cigarette?" The association between recalled exposure to POS cigarette marketing and cravings was estimated using ordinary least squares linear regression models, controlling for nicotine dependence, gender, age, race/ethnicity, income, education, frequency of visiting stores in one's neighbourhood and method of recruitment into the study.

Results

Recalled exposure to POS cigarette displays (p<0.001) and advertisements (p=0.002), but not promotions (p=0.06), was associated with more frequent cravings to smoke.

Conclusions

Recalled exposure to POS cigarette marketing is associated with cravings to smoke as predicted by laboratory studies on the effects of smoking cues on cigarette craving. Policies that reduce or eliminate POS cigarette marketing could reduce cigarette cravings and might attenuate impulse buying of cigarettes.

To address the illicit cigarette trade, the European Union (EU) has signed agreements with the four major Transnational Tobacco Companies (TTCs) that involve establishing extensive systems of cooperation. All agreements foresee two types of payments: annual payments (totalling US$ 1.9 billion over 20 years) and supplementary seizure payments, equivalent to 100% of the evaded taxes in the event of seizures of their products. While limited by the fundamental lack of transparency in this area, our analysis suggests that these agreements have served largely to secure the TTCs’ interests and are threatening progress in tobacco control. The seizure payments are paltry and a wholly inadequate deterrent to TTC involvement in illicit trade. Despite the agreements, growing evidence indicates the TTCs remain involved in the illicit trade or are at best failing to secure their supply chains as required by the agreements. The intention of the seizure-based payments to deter the tobacco industry from further involvement in the illicit cigarette trade has failed because the agreements contain too many loopholes that provide TTCs with both the incentive and opportunity to classify seized cigarettes as counterfeit. In addition, the shifting nature of cigarette smuggling from larger to smaller consignments often results in seizures that are too small to qualify for the payments. Consequently, the seizure payments represent a tiny fraction of the revenue lost from cigarette smuggling, between 2004 and 2012, 0.08% of the estimated losses due to illicit cigarette trade in the EU. Our evidence suggests the EU should end these agreements.]]>2015-05-28T15:30:23-07:00info:doi/10.1136/tobaccocontrol-2014-052218hwp:master-id:tobaccocontrol;tobaccocontrol-2014-052218BMJ Publishing Group Ltd2015-05-28Special communicationshttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2015-052398v1?rss=1
The tobacco industry regularly uses the threat of increased illicit cigarette trade to dissuade governments from implementing prohealth policies. Illicit trade is the number one argument used by the tobacco lobby to oppose tobacco tax increases,1 and is also being used against implementation of other major tobacco control measures such as plain packaging, display bans and pack size restrictions.2

Studies funded and presented by cigarette manufacturers and their business associations are generally not peer-reviewed or replicable and therefore, do not meet standards of academic research.3 A growing body of evidence suggests that estimates of the illicit cigarette trade levels presented in the industry-commissioned reports are often inflated.4–10

Another tactic used by the tobacco industry to exaggerate the scope of the illicit cigarette trade problem is to use illicit cigarette market share rather...]]>

This study examined how effectively current policy measures control depictions of tobacco in Mongolian language YouTube videos.

Methods

A search of YouTube videos using the Mongolian term for ‘tobacco’, and employing ‘relevance’ and ‘view count’ criteria, resulted in a total sample of 120 videos, from which 38 unique videos were coded and analysed.

Results

Most videos were antismoking public service announcements; however, analyses of viewing patterns showed that pro-smoking videos accounted for about two-thirds of all views. Pro-smoking videos were also perceived more positively and had a like:dislike ratio of 4.6 compared with 3.5 and 1.5, respectively, for the magic trick and antismoking videos. Although Mongolia prohibits tobacco advertising, 3 of the pro-smoking videos were made by a tobacco company; additionally, 1 pro-smoking video promoted electronic cigarettes.

Conclusions

Given the popularity of Mongolian YouTube videos that promote smoking, policy changes are urgently required to control this medium, and more effectively protect youth and young adults from insidious tobacco marketing.

Although tobacco packages have evolved to feature health warnings and, in Australia, dissuasive colours, the format of on-pack cessation information has not changed. We compared how alternative Quitline information formats affected smokers’ perceptions and choice behaviours, and their likelihood of seeking cessation support.

Methods

We conducted an online study comprising a choice experiment using a two (number of panels) by three (panel position: above, middle, below) plus control (current format) design, and a between-subjects comparison of a two-panel format and the control. The sample comprised 608 New Zealand smokers.

Results

Relative to the current format, respondents regarded each test format as more effective in communicating cessation information (p<0.0001), particularly the two-panel formats. Respondents found the two-panel format tested via paired comparisons significantly easier to read, more visually salient and more likely than the control to encourage them and other smokers to consider quitting (all p<0.0001). Heat map comparisons showed that the Quitline number and affirming message were significantly more salient in the test format than in the current format (p<0.0001), although the headline and warning explanation were more salient in the control.

Conclusions

Reformatting Quitline information could improve its visual salience and readability and capitalise on the dissonance that pictorial warning labels and plain packaging create. Enhancing stimuli that may prompt smokers to try and quit, affirming their decision to do so and prompting the use of cessation support could increase the number and success of quit attempts.

Australian tobacco companies have introduced evocative variant names that could re-create the aspirational connotations plain packaging aims to remove. To inform future regulation, we explored how brand descriptors affected smokers’ responses to plain packs featuring different variant name combinations.

Methods

An online survey of 254 daily smokers or social smokers aged between 18 and 34 used a within-subjects best-worst experiment to estimate the relative effects of variant names. A 2x4x4x4 design contained four attributes: quality (premium or none), taste (smooth, fine, rich or none) connotation (classic, midnight, infinite or none) and colour (red, blue, white or none). In a between-subjects component, respondents evaluated one of two alternative packs according to its perceived harm and ease of quitting.

Results

The most important variant attribute was connotation, followed by taste, colour and quality; within these attributes, the most attractive descriptors were ‘classic’ and ‘smooth’. We identified four distinct segments that differed significantly in their sociodemographic attributes and variant preferences, although not in their perceptions of the harm or quitting ease associated with two different variants.

Conclusions

Some descriptors significantly enhance the appeal of tobacco products among different groups of smokers and may undermine plain packaging's dissuasive intent. Policymakers should explicitly regulate variant names to avoid the ‘poetry on a package’ evident in Australia. Options include disallowing new descriptors, limiting the number of descriptors permitted or banning descriptors altogether.

An essential component of evaluating potential modified risk tobacco products is to determine how consumers use the product and resulting effects on biomarkers of toxicant exposure.

Study design

Cigarette smokers (n=391) recruited in Minnesota and Oregon were randomised to either snus or 4 mg nicotine gum for 12 weeks. Participants were instructed to completely switch from cigarettes to these products. Urine samples were collected to analyse for carcinogenic tobacco-specific nitrosamine metabolites (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and N'-nitrosonornicotine and their glucuronides) and nicotine metabolites (total cotinine and nicotine equivalents) levels.

Results

Of the 391 participants randomised, 52.9% were male, the mean±SD age was 43.9±12.5 years, baseline number of cigarettes/day was 18.0±6.5 and Fagerstrom Test for Nicotine Dependence score was 5.1±2.0. The mean±SD number of snus pouches used/week at week 6 prior to tapering was 39.1±24.0 and nicotine gum pieces used was 37.6±26.3. Dual use of cigarettes and these products were observed in 52.9% and 58.2% of those assigned to snus and nicotine gum, respectively, at week 12. The end of treatment biochemically verified (carbon monoxide, CO <6 ppm) 7-day avoidance of cigarettes was 21.9% in the snus group and 24.6% in the nicotine gum group. Toxicant exposure in the nicotine gum group was significantly less when compared to snus.

Conclusions

Snus performed similarly to nicotine gum in cigarette smokers who were interested in completely switching to these products, but was associated with less satisfaction and greater toxicant exposure than nicotine gum.

Jonathan Daniel Heck, PhD, a board certified toxicologist, career scientist at Lorillard Tobacco, and industry expert on menthol, served as an industry representative on the Food and Drug Administration (FDA) Tobacco Products Scientific Advisory Committee (TPSAC) from 2010 through 2014. In 2011, Heck was the lead author of the "Industry Menthol Report; Menthol Cigarettes: No Disproportionate Impact on Public Health"1 submitted to the FDA.

To become certified and maintain his status as a board certified toxicologist, Heck took a certification examination and multiple recertification examinations administered by the American Board of Toxicology. Initial certification required passage of a three-part examination. Recertification occurs through an open-book examination.2

On 11 July 1996, Heck sent a memo to his supervisor at Lorillard describing his plans for completing the American Board of Toxicology recertification examination, saying: "This is a nuisance, but I need to spend some ‘quality time’ on this 300-question, every...]]>

Knowledge about the harms of tobacco use deters initiation and is associated with cessation. Most studies on this knowledge in the general population have been in high-income countries, but the tobacco use burden is increasing in low-income and middle-income countries. We sought to estimate levels of knowledge about tobacco-related diseases in 22 countries and determine the factors associated with differences in knowledge.

Methods

We used data from the Global Adult Tobacco Survey (GATS), a nationally representative survey of persons aged ≥15 years. GATSs were conducted from 2008 to 2013 in 22 low-income and middle-income countries. Information was gathered on tobacco-related knowledge and noticing of antismoking mass media messages and health warning labels on cigarette packages. We constructed a four-point knowledge scale and performed multivariate regression analyses.

Results

Median country values for the proportion of adults who believed smoking causes a specific illness were 95.9% for lung cancer, 82.5% for heart attack and 74.0% for stroke. Knowledge scores ranged from 2.1 to 3.8. In multivariate regressions, adults scored significantly higher on the knowledge scale if they noticed antismoking media messages (22 countries) or health warning labels (17 countries). Significantly higher knowledge scores occurred in all 9 countries with pictorial health warning labels compared with only 8 out of 13 countries with text-only warning labels.

Conclusions

Antismoking media messages appear effective for warning the public about the harms from tobacco use in all 22 countries, while warning labels are effective in the majority of these countries. Our findings suggest opportunities to motivate smoking cessation globally.

To inform international research and policy, we conducted a meta-analysis of the experimental literature on pictorial cigarette pack warnings.

Data sources

We systematically searched 7 computerised databases in April 2013 using several search terms. We also searched reference lists of relevant articles.

Study selection

We included studies that used an experimental protocol to test cigarette pack warnings and reported data on both pictorial and text-only conditions. 37 studies with data on 48 independent samples (N=33 613) met criteria.

Data extraction and synthesis

Two independent coders coded all study characteristics. Effect sizes were computed from data extracted from study reports and were combined using random effects meta-analytic procedures.

Results

Pictorial warnings were more effective than text-only warnings for 12 of 17 effectiveness outcomes (all p<0.05). Relative to text-only warnings, pictorial warnings (1) attracted and held attention better; (2) garnered stronger cognitive and emotional reactions; (3) elicited more negative pack attitudes and negative smoking attitudes and (4) more effectively increased intentions to not start smoking and to quit smoking. Participants also perceived pictorial warnings as being more effective than text-only warnings across all 8 perceived effectiveness outcomes.

Conclusions

The evidence from this international body of literature supports pictorial cigarette pack warnings as more effective than text-only warnings. Gaps in the literature include a lack of assessment of smoking behaviour and a dearth of theory-based research on how warnings exert their effects.

Preference for flavour capsules increased significantly in Mexico (6% to 14%) and Australia (1% to 3%), but not in the USA (4% to 5%). 18–24 year olds were most likely to prefer capsules in the USA (10%) and Australia (4%), but not Mexico. When compared to smokers who preferred regular brands, smokers who preferred brands with capsules viewed their variety of cigarettes as having more positive appeal (all countries), better taste (all countries), and lesser risk (Mexico, USA) than other brand varieties.

Conclusions

Results indicate that use of cigarettes with flavour capsules is growing, is associated with misperceptions of relative harm, and differentiates brands in ways that justify regulatory action.

The US Food and Drug Administration (FDA) Center for Tobacco Products (CTP) receives and reviews voluntary reports from consumers, healthcare professionals and members of the public on adverse experiences (AEs) associated with tobacco products. Reports from consumers and concerned citizens have described AEs not only in users, but also in non-users of e-cigarettes.12

AE reports received by FDA between 1 January 2012 and 31 December 2014 were reviewed to evaluate AEs associated with e-cigarettes in non-users. The reports were received via the Safety Reporting Portal, MedWatch, mail and email. Of 136 reports related to e-cigarette AEs, 40 involved non-users (table 1).

To measure the implementation of WHO Framework Convention on Tobacco Control (FCTC) Article 5.3 at country level using a new Tobacco Industry Interference Index and to report initial results using this index in seven Southeast Asian countries.

Methods

Score sheet based on WHO FCTC Article 5.3 Guidelines sent to correspondents in seven Southeast Asian countries, using a scoring system designed with the help of tobacco control experts and validated through focused group discussions.

Results

The seven countries ranked from the lowest level of interference to the highest are Brunei, Thailand, Lao PDR, Cambodia, Philippines, Malaysia and Indonesia. Countries that face high levels of unnecessary interaction with the tobacco industry also face high levels of tobacco industry influence in policy development. Most governments do not allow any tobacco industry representatives on their delegation to sessions of the Conference of the Parties or its subsidiary bodies nor accept their sponsorship for delegates, but most governments still accept or endorse offers of assistance from the tobacco industry in implementing tobacco control policies. Most governments also receive tobacco industry contributions (monetary or in kind) or endorse industry corporate social responsibility activities. Governments do not have a procedure for disclosing interactions with the tobacco industry, but Lao PDR, Philippines and Thailand have instituted measures to prevent or reduce industry interference.

Conclusions

This Tobacco Industry Interference Index, based on the WHO FCTC Article 5.3 Guidelines, is a useful advocacy tool for identifying both progress and gaps in national efforts at implementing WHO FCTC Article 5.3.

Regulatory imbalances exist in the treatment of cigarettes and non-cigarette tobacco products in the USA. We assessed whether declines in cigarette consumption during 2002–2012 were offset by increased use of non-cigarette tobacco products—cigars, pipes, roll-your-own (RYO) and smokeless tobacco.

Methods

Industry-reported taxable removals (actual sales) were converted into packs for cigarettes and cigarette pack equivalents (CPEs) for loose tobacco (RYO plus pipe tobacco) and moist snuff. Cigars were not converted to CPEs because of their heterogeneity in size/tobacco content. Per capita sales were calculated for the US adult population aged ≥18 years based on the US Census Bureau data. Self-reported data on current (past 30-day) tobacco use among US adults aged ≥18 years were from the National Survey on Drug Use and Health (NSDUH). Joinpoint and logistic regression were used to assess linear trends during 2002–2012.

Results

During 2002–2012, cigarette sales declined from 96.91 to 59.85 cigarette packs per capita; increases occurred for sale of cigars (30.51–57.42 cigars per capita), loose tobacco (2.50–5.63 CPEs per capita) and moist snuff (10.64–14.58 CPEs per capita; all p<0.05 for trend). Self-reported current cigarette smoking declined during 2002–2012 (27.4–23.6%); increases were noted for current RYO (2.6–3.6%) and smokeless tobacco use (3.5–3.7%; all p<0.05 for trend).

Conclusions

The increase in non-cigarette tobacco consumption is a public health concern because all tobacco products are harmful. Eliminating imbalances in tax structure and regulations between cigarettes and non-cigarette tobacco products may help reduce aggregate tobacco consumption.

To determine the most prominent individual and interpersonal triggers to quit smoking in China and their associations with sociodemographic characteristics.

Methods

Data come from Waves 1–3 (2006–2009) of the International Tobacco Control (ITC) China Survey, analysed cross-sectionally as person-waves (N=14 358). Measures included sociodemographic and smoking characteristics. Those who quit between waves (4.3%) were asked about triggers that ‘very much’ led them to stop smoking, and continuing smokers about triggers that ‘very much’ made them think about quitting. Triggers covered individual (personal health concerns, cigarette price, smoking restrictions, advertisements, warning labels) and interpersonal factors (family/societal disapproval of smoking, setting an example to children, concerns about secondhand smoke).

Results

Over a third of respondents (34.9%) endorsed at least one trigger strongly; quitters were more likely than smokers to mention any trigger. While similar proportions of smokers endorsed individual (24.4%) and interpersonal triggers (24.0%), quitters endorsed more individual (61.1%) than interpersonal (48.3%) triggers. However, the most common triggers (personal health concerns; setting an example to children) were the same, endorsed by two-thirds of quitters and a quarter of smokers, as were the least common triggers (warning labels; cigarette price), endorsed by 1 in 10 quitters and 1 in 20 smokers. Lower dependence among smokers and greater education among all respondents were associated with endorsing any trigger.

Conclusions

Individual rather than interpersonal triggers appear more important for quitters. Major opportunities to motivate quit attempts are missed in China, particularly with regard to taxation and risk communication. Interventions need to focus on more dependent and less-educated smokers.

A recent report showed that 13.1% of US middle and high school students were exposed to tobacco coupons in the past 30 days in 2012. The current study reanalysed data from the National Youth Tobacco Survey 2012 to examine the associations between exposure to tobacco coupons in the past 30 days and predictors of smoking among US youth, by smoking status.

Methods

24 658 middle and high school students were asked if and where they had received tobacco coupons in the past 30 days. Demographics, smoking behaviours, smoking-related beliefs, susceptibility to smoking and confidence in quitting smoking were assessed. Analyses were stratified by smoking status (never smokers, experimenters and current smokers). Data were weighted to be representative of the US youth.

Results

Exposure to tobacco coupons was associated with lower likelihood of denying the social benefits of cigarette smoking and believing all tobacco products are dangerous; higher likelihood of being susceptible to smoking (among never smokers); lower likelihood to feel confident in quitting cigarettes completely (among current smokers); and higher likelihood to intend to purchase cigarettes in the next 30 days (among experimenters and current smokers; p<0.05).

Conclusions

Tobacco coupons may promote smoking and hinder smoking cessation among youth. Regulating tobacco coupons may reduce youth smoking in the USA. Further research is needed to determine the effect of tobacco coupons on youth tobacco use globally.

Background

Most e-cigarette liquids contain flavour chemicals. Flavour chemicals certified as safe for ingestion by the Flavor Extracts Manufacturers Association may not be safe for use in e-cigarettes. This study identified and measured flavour chemicals in 30 e-cigarette fluids.

Methods

Two brands of single-use e-cigarettes were selected and their fluids in multiple flavour types analysed by gas chromatography/mass spectrometry. For the same flavour types, and for selected confectionary flavours (eg, bubble gum and cotton candy), also analysed were convenience samples of e-cigarette fluids in refill bottles from local ‘vape’ shops and online retailers.

Results

In many liquids, total flavour chemicals were found to be in the ~1–4% range (10–40 mg/mL); labelled levels of nicotine were in the range of 0.6–2.4% (6 to 24 mg/mL). A significant number of the flavour chemicals were aldehydes, a compound class recognised as ‘primary irritants’ of mucosal tissue of the respiratory tract. Many of the products contained the same flavour chemicals: vanillin and/or ethyl vanillin was found in 17 of the liquids as one of the top three flavour chemicals, and/or at ≥0.5 mg/mL.

Conclusions

The concentrations of some flavour chemicals in e-cigarette fluids are sufficiently high for inhalation exposure by vaping to be of toxicological concern. Regulatory limits should be contemplated for levels of some of the more worrisome chemicals as well as for total flavour chemical levels. Ingredient labeling should also be required.

The vast majority of tobacco users began before the age of 21. Raising the tobacco sales age to 21 has the potential to reduce tobacco use initiation and progression to regular smoking. Our objective was to assess the level of public support nationally for ‘Tobacco 21’ initiatives in the USA.

Methods

The Social Climate Survey of Tobacco Control, a cross-sectional dual-frame survey representing national probability samples of adults was administered in 2013. Respondents were asked to state their agreement level with, ‘The age to buy tobacco should be raised to 21.’

Results

Of 3245 respondents, 70.5% support raising the age to buy tobacco to 21. The majority of adults in every demographic and smoking status category supported raising the tobacco sales age to 21. In multivariable analyses, support was highest among never smokers, females, African-Americans and older adults.

Conclusions

This national study demonstrates broad public support for raising the sales age of tobacco to 21 and will help facilitate wide dissemination of initiatives to increase the legal purchase age at national, state and local levels. Increasing public awareness about the susceptibility and rapid addiction of youth to nicotine may further increase public support for raising the tobacco sale age to 21.

Longitudinal data of smokers from two survey waves of the International Tobacco Control (ITC) Europe Surveys were used. In France and the UK, pictorial warning labels were implemented on the back of cigarette packages between the two survey waves. In Germany and the Netherlands, the text warning labels did not change.

Findings

Warning salience decreased between the surveys in France (OR=0.81, p=0.046) and showed a non-significant increase in the UK (OR=1.30, p=0.058), cognitive responses increased in the UK (OR=1.34, p<0.001) and decreased in France (OR=0.70, p=0.002), forgoing cigarettes increased in the UK (OR=1.65, p<0.001) and decreased in France (OR=0.83, p=0.047), and avoiding warnings increased in France (OR=2.93, p<0.001) and the UK (OR=2.19, p<0.001). Warning salience and cognitive responses decreased in Germany and the Netherlands, forgoing did not change in these countries and avoidance increased in Germany. In general, these changes in warning label responses did not differ by education. However, in the UK, avoidance increased especially among low (OR=2.25, p=0.001) and moderate educated smokers (OR=3.21, p<0.001).

Conclusions

The warning labels implemented in France in 2010 and in the UK in 2008 with pictures on one side of the cigarette package did not succeed in increasing warning salience, but did increase avoidance. The labels did not increase educational inequalities among continuing smokers.

Reduction of the availability of tobacco has been proposed as a means of reducing and denormalising tobacco use. Some retailers have stopped selling tobacco. Therefore, we investigated how willing New Zealand convenience store owners were to stop selling tobacco or sell nicotine replacement therapy. Promotion of their stores was offered as an incentive to stop selling tobacco.

Methods

We asked convenience store owners in the Auckland metropolitan region of New Zealand to choose one of three actions. The first was to stop selling tobacco for a short period of time; the second was to restrict the hours that they sold tobacco; the third was to display and sell nicotine replacement therapy. All participating retailers completed a short interview about selling tobacco. We also surveyed customers about nicotine replacement and cessation.

Results

One-third of eligible retailers agreed to participate. Most who participated (93%) were unwilling to stop or restrict tobacco sales and 2 (7%) had already stopped selling tobacco. Tobacco was perceived as a key product for their businesses. Very few customers who purchased cigarettes noticed nicotine replacement therapy or obtained it from convenience stores.

Conclusions

Substantially reducing the availability of tobacco in communities is likely to require legislative approaches, underpinned by sustained community pressure and support for convenience store owners who are willing to change their business model.

To examine the association between exposure to secondhand smoke (SHS) in the home and mental health among children.

Methods

Cross-sectional study of 2357 children representative of the Spanish population aged 4–12 years in 2011–2012. Duration of SHS exposure in children was reported by parents. Probable mental disorder was defined as a score >90th centile in the parental version of the Strengths and Difficulties Questionnaire (SDQ). Statistical analysis was performed with logistic regression and adjusted for sociodemographic variables, lifestyle, neighbourhood environment and family characteristics, including parental mental health.

Results

Among study participants, 6.9% (95% CI 5.7% to 8.0%) were exposed to SHS in the home for <1 h/day and 4.5% (95% CI 3.5% to 5.5%) for ≥1 h/day. Compared to children not habitually exposed to SHS, the multivariate ORs for probable mental disorder were 1.49 (95% CI 0.85 to 2.62) for SHS exposure <1 h/day and 2.73 (95% CI 1.38 to 5.41) for SHS exposure ≥1 h/day (p for linear trend=0.002). The corresponding ORs for attention-deficit and hyperactivity disorder (ADHD) were 2.18 (95% CI 1.30 to 3.64) for <1 h/day exposure and 3.14 (95% CI 1.63 to 6.04) for ≥1 h/day exposure (p for linear trend <0.001). No association was found between SHS and the rest of the components of the SDQ.

Conclusions

Among children, SHS exposure in the home during ≥1 h/day is associated with a higher frequency of mental disorder. This association was mostly due to the impact of SHS on ADHD.

Studies were independently selected by two reviewers, with a study outcome of tobacco use and a population of conflict-affected civilian populations such as internally displaced persons, refugees, residents in conflict-affected areas, residents and returning forcibly displaced populations returning in stabilised and postconflict periods. 2863 studies were initially identified.

Data extraction

Data were independently extracted. The Quality Assessment Tool for Quantitative Studies and the Critical Appraisal Skills Programme for qualitative studies were used to assess study quality.

Data synthesis

39 studies met inclusion criteria and descriptive analysis was used. Findings were equivocal on the effect of conflict on tobacco use. Evidence was clearer on associations between post-traumatic stress and other mental disorders with nicotine dependence. However, there were too few studies for definitive conclusions. No study examined the effectiveness of tobacco-related interventions. The quantitative studies were moderate (N=13) or weak (N=22) quality, and qualitative studies were moderate (N=3) or strong (N=2).

Conclusions

Some evidence indicates links between conflict and tobacco use but substantially more research is required.

In this commentary we consider the validity of tobacco industry-funded research on the effects of standardised packaging in Australia. As the first country to introduce standardised packs, Australia is closely watched, and Philip Morris International has recently funded two studies into the impact of the measure on smoking prevalence. Both of these papers are flawed in conception as well as design but have nonetheless been widely publicised as cautionary tales against standardised pack legislation. Specifically, we focus on the low statistical significance of the analytical methods used and the assumption that standardised packaging should have an immediate large impact on smoking prevalence.]]>2015-03-05T01:11:49-08:00info:doi/10.1136/tobaccocontrol-2014-052051hwp:master-id:tobaccocontrol;tobaccocontrol-2014-052051BMJ Publishing Group Ltd2015-03-05Commentarieshttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2014-051919v1?rss=1
Background

The 2014 European Union (EU) Tobacco Products Directive (TPD) was negotiated in a changed policy context, following adoption of the EU's ‘Smart Regulation’ agenda, which transnational tobacco companies (TTCs) anticipated would increase their influence on health policy, and the WHO Framework Convention on Tobacco Control (FCTC), which sought to reduce it. This study aims to explore the scale and nature of the TTCs' lobby against the EU TPD and evaluate how these developments have affected their ability to exert influence.

The lobby was massive. PMI alone employed over 160 lobbyists. Strategies mainly used third parties. Efforts to 'Push' (amend) or 'Delay' the proposal and block 'extreme policy options' were partially successful, with plain packaging and point of sales display ban removed during the 3-year delay in the Commission. The Smart Regulation mechanism contributed to changes and delays, facilitating meetings between TTC representatives (including ex-Commission employees) and senior Commission staff. Contrary to Article 5.3, these meetings were not disclosed.

Conclusions

During the legislative process, Article 5.3 was not consistently applied by non-health Directorates of the European Commission, while the tools of the Smart Regulation appear to have facilitated TTC access to, and influence on, the 2014 TPD. The use of third parties undermines Article 5.3.

This study uses an online survey panel to compare two approaches for assessing ad awareness. The first uses a screenshot of a television ad and the second shows participants a full-length video of the ad.

Methods

We randomly assigned 1034 Minnesota respondents to view a screenshot or a streaming video from two antitobacco ads. The study used one ad from ClearWay Minnesota's We All Pay the Price campaign, and one from the Centers for Disease Control Tips campaign. The key measure used to assess ad awareness was aided ad recall. Multivariate analyses of recall with cessation behaviour and attitudinal beliefs assessed the validity of these approaches.

Results

The respondents who saw the video reported significantly higher recall than those who saw the screenshot. Associations of recall with cessation behaviour and attitudinal beliefs were stronger and in the anticipated direction using the screenshot method. Over 20% of the respondents assigned to the video group could not see the ad. People who were under 45 years old, had incomes greater than $35 000 and women were reportedly less able to access the video.

Conclusions

The methodology used to assess recall matters. Campaigns may exaggerate the successes or failures of their media campaigns, depending on the approach they employ and how they compare it to other media campaign evaluations. When incorporating streaming video, researchers should consider accessibility and report possible response bias. Researchers should fully define the measures they use, specify any viewing accessibility issues, and make ad comparisons only when using comparable methods.

The intersection between gender and class can aid in understanding gender differences in smoking.

Aim

To analyse how changes in gender inequality relate to differences in smoking prevalence by gender, education and birth cohort in Spain over the past five decades (1960–2010).

Methods

The Gender Inequality Index (GII) was calculated in 5-year intervals from 1960 to 2010. GII ranges from 0 to 1 (1=highest inequality) and encompasses three dimensions: reproductive health, empowerment and labour market. Estimates of female and male smoking prevalence were reconstructed from representative National Health Surveys and stratified by birth cohort and level of education. We calculated female-to-male smoking ratios from 1960 to 2010 stratified by education and birth cohort.

Results

Gender inequality in Spain decreased from 0.65 to 0.09 over the past 50 years. This rapid decline was inversely correlated (r=–0.99) to a rising female-to-male smoking ratio. The youngest birth cohort of the study (born 1980–1990) and women with high education levels had similar smoking prevalences compared with men. Women with high levels of education were also the first to show a reduction in smoking prevalence, compared with less educated women.

Conclusions

Gender inequality fell significantly in Spain over the past 50 years. This process was accompanied by converging trends in smoking prevalence for men and women. Smoking prevalence patterns varied greatly by birth cohort and education levels. Countries in earlier stages of the tobacco epidemic should consider gender-sensitive tobacco control measures and policies.

Data were from the International Tobacco Control (ITC) longitudinal cohort survey assessing Australian smokers one wave prior to the policy change in 2011 (n=1104) and another wave after the policy change in 2013 (n=1093). We assessed initial attentional orientation (AO) to or away from warnings, plus other reactions, including cognitive reactions towards the HWLs and quit intentions.

Results

As expected, AO towards the HWLs and reported frequency of noticing warnings increased significantly after the policy change, but not more reading. Smokers also thought more about the harms of smoking and avoided the HWLs more after the policy change, but frequency of forgoing cigarettes did not change. The subgroup that switched from initially focusing away to focusing on the HWLs following the policy change noticed and read the HWLs more, and also thought more about the harmful effects of smoking, whereas the subgroup (5.4%) that changed to focusing away from the HWLs showed opposite effects. We tested the mediational model of Yong et al and confirmed it for predicting quit intentions, with larger effects post-policy.

Conclusions

Increasing the size of HWLs and introducing them on PP in Australia appears to have led to an overall increase in desired levels and strength of some reactions, but evidence of reactance was among a small minority.

South Korea increased tobacco taxes in 2015 after a 10-year gap. This commentary suggests two lessons for public finance practitioners. Substantive tax increases are crucial to reducing tobacco use; particularly where prices are demonstrably lower and prevalence higher in comparison to other countries ranked similarly on economic development indicators. Second, as a rule of thumb, governments cannot afford to neglect the annual increases that ensure that tobacco taxes do not lose their efficacy over time.]]>2015-02-11T09:00:50-08:00info:doi/10.1136/tobaccocontrol-2014-052104hwp:master-id:tobaccocontrol;tobaccocontrol-2014-052104BMJ Publishing Group Ltd2015-02-11Commentarieshttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2014-051860v1?rss=1
Background

New York City (NYC) raised the minimum purchase age for cigarettes from 18 to 21 on 1 August 2014. The new law is intended to decrease current smoking rates and smoking initiation among the city's youth. Assessment of compliance with existing cigarette sales and tax laws could aid in determining what may be needed for successful implementation of the city's new law.

Purpose

To assess compliance with minimum sales price and purchase age laws in NYC, before change in law.

Methods

Ten trained field investigators purchased cigarettes from different types of retailers throughout all five NYC boroughs, resulting in 421 purchases. Investigators noted whether they were asked for identification and the price of their purchase. Multivariable logistic and Ordinary Least Squares regression techniques were used to assess predictors of retailer compliance with sales price and minimum purchase age laws.

Results

In 29% of purchases, investigators did not have to produce identification (p<0.05) to purchase cigarettes. Only 3.1% of sales were at prices lower than the minimum sales price. City borough was significantly associated with purchase without identification (p<0.001) and mean sales price (p<0.024). Vendor type (independent vs chain) was significantly related to investigators being able to purchase cigarettes without identification (p<0.001).

Conclusions

Variation in compliance with existing laws suggests that more active monitoring of compliance with the new minimum legal purchase age will be required in order to realise the new law's public health potential.

As smoking is increasingly de-normalised, different messages may become more appropriate for use in tobacco control advertisements to reflect the changing social environment. To date, more commonly used messages have included fear appeals relating to physical health and guilt appeals focusing on the effects of smoking on loved ones.

Objective

This study investigated the relative effectiveness of varying advertising appeals to promote smoking cessation. The study was conducted in Australia, where only 12% of the population smokes and legislation restricts smoking in many public places. The aim was to provide insight into ways to motivate the small segment of existing smokers to consider quitting.

Methods

Across a qualitative phase and an ad testing phase, shame was found to be highly salient to current smokers and those who had quit recently. On the basis of these results, a television advertisement featuring a shame appeal was developed and broadcast. The ad featured various scenarios of individuals hiding their smoking from others. The campaign was evaluated using the measures of awareness, believability, perceived relevance and smoking behaviours.

Results

The shame appeal television advertisement was found to resonate with smokers and encourage quitting/reducing behaviours. Around 4 in 5 (78%) smokers surveyed recalled seeing the ad, almost all of whom could nominate at least one correct take-out message (94%). Around three-quarters (72%) found the ad to be personally relevant and half (53%) reported that they had successfully quit, attempted to quit or cut down the number of cigarettes they smoked since the start of the campaign.

Conclusions

The use of shame appeals may be an effective method of motivating smokers to quit in an environment where they are members of a small minority and supportive legislation exists to discourage smoking in public places.

We investigated the impact of cigarette price differences across the European Union (EU) on cross-border tobacco purchasing because of cheaper price among current cigarette smokers.

Methods

Individual-level tobacco-related data (including cross-border tobacco purchasing behavior) were from the Special Eurobarometer 385 (V.77.1), a cross-sectional survey of persons aged ≥15 years from 27 EU Member States during 2012. Country-specific weighted average prices (WAP) per 1000 cigarettes (as of 1 July 2012) were obtained from the European Commission, and divided by 50 to yield WAP per cigarette pack. The dispersion in EU cigarette prices was measured with the coefficient of variation. Multivariate logistic regression was applied to measure the relationship between EU-wide cigarette price differential and cross-border tobacco purchasing because of cheaper price among current cigarette smokers (n=6896).

Results

The coefficient of variation for cigarette WAP within the EU was 0.39 (mean price=3.99/pack). Of all current cigarette smokers in the EU, 26.2% (27.5 million persons) engaged in a cross-border tobacco purchase within the past 12 months, of which 56.3% did so because of cheaper price in another country. EU-wide cigarette price differential was significantly associated with making a cross-border tobacco purchase because of cheaper price (adjusted OR=1.34; 95% CI 1.22 to 1.47).

Conclusions

Reducing differences in cigarette tax and price within the EU, coupled with a stricter limitation on the quantity of cigarettes that it is possible to carry from one Member State to another, may help reduce cross-border tax avoidance strategies.

It is now over 10 years since a New Zealand law1 requiring all preschools and schools to become completely smoke-free (including all grounds) became operational in 2004. Previously, indoor school areas had been required to be largely smoke-free, but there was ‘variable compliance’.23 As there is limited literature on the international long-term experience (outside of California4) with laws covering outdoor areas such as school grounds, we briefly reviewed the experience with this New Zealand law.

Methods

Literature searches using PubMed, MEDLINE and Google Scholar were performed for the period 1 January 2004 to 17 June 2014. These were all focused on the New Zealand setting (preschools, schools and smoking).

Results

There was some evidence that the implementation of the law went relatively well. A survey published in 2006 of 134 primary schools found that 79% "reported no difficulty in implementing the Act".

Exposure to the emissions of a tobacco waterpipe is associated with increased health risks among its users as well as those exposed to its secondhand smoke. Waterpipe use is an emerging concern to the tobacco control community, particularly among countries of the Eastern Mediterranean Region. In 2002, Qatar adopted legislation that prohibited cigarette smoking inside public venues, but exempted tobacco waterpipe smoking. To inform the development and enforcement of effective policy, the impact of cigarette and waterpipe use on indoor air quality was monitored in waterpipe cafes in Doha, Qatar.

Methods

Particulate matter (PM2.5) levels were measured inside and outside of a sample of 40 waterpipe cafes and 16 smoke-free venues in Doha, Qatar between July and October 2012. In addition, the number of waterpipes being smoked and the number of cigarette smokers were counted within each venue. Non-paired and paired sample t tests were used to assess differences in mean PM2.5 measurements between venue type (waterpipe vs smoke-free) and environment (indoor vs outdoor).

Elevated levels of particulate pollution were found in waterpipe cafes in Doha, Qatar, potentially endangering the health of employees and patrons. To protect the public from the dangers of secondhand tobacco smoke, and to change social norms around tobacco use, smoke-free policies that apply to all forms of combusted tobacco products, including the waterpipe, are needed.

Multiunit housing (MUH) residents are susceptible to secondhand smoke (SHS) exposure, which can transfer between living units. This review summarises existing scientific literature relevant to smoke-free MUH, discusses knowledge gaps and provides recommendations for future research to inform public health action.

Data sources

We conducted a systematic search of peer-reviewed articles using three databases: EBSCOhost CINAHL, PubMed and Web of Science.

Study selection

Article titles, abstracts and text were reviewed to ascertain three inclusion criteria: (1) English language; (2) conducted in the USA; (3) reported on baseline data, development, implementation or evaluation of smoke-free MUH.

Data extraction

We used a multistep process to identify eligible articles: (1) two reviewers separately evaluated article titles; (2) two reviewers separately evaluated abstracts and (3) one reviewer read each article and determined inclusion eligibility.

Data synthesis

We identified and included 35 articles published during 2001–2014, grouped based on broad themes: MUH resident (n=16); MUH operator (n=6); environmental monitoring and biomarkers (n=9); economic (n=2); legal (n=3); and implementation process and policy impact (n=8). Studies with multiple themes were included in all relevant groups.

Conclusions

Existing literature has focused on self-reported, cross-sectional studies of MUH residents and operators; some studies of environmental markers, biomarkers and economic indicators have also been conducted. Future research on smoke-free MUH policy compliance and enforcement, and on the impact of these policies on smoking behaviours and health outcomes, could further inform public health planning, policy and practice. Despite these gaps, the current literature provides sufficient evidence for action to eliminate SHS exposure in MUH.

This qualitative research explores the use of electronic cigarettes and other similar ‘vapor’ delivery devices among young adults in New York City.

Methods

We employed 17 focus groups followed by 12 semistructured interviews to understand the beliefs, opinions and practices related to the use of electronic cigarettes among young adult smokers (N=87).

Results

Participants were mainly daily (52%) and non-daily (41%) smokers. While experimentation with electronic cigarette devices was frequently reported, participants related an overall lack of information about the devices and what they did know often reflected messages in e-cigarette marketing campaigns. Participants also used their own bodily sensations as a way to gauge potential risks and benefits of the products. Finally, young adults, steeped in a culture of personal technologies, perceived e-cigarettes as one more ‘toy’ among other technologies integrated into their everyday lives.

Discussion

E-cigarettes were also frequently used with other tobacco products, including conventional cigarettes. Our research indicates that public health campaigns may be needed to counter current industry marketing and inform the public that electronic cigarettes are currently unregulated, understudied and contain toxicants and carcinogens.

In 2013, the State of Minnesota Legislature passed a tobacco tax increase that increased the combined cigarette excise and sales tax by US$1.75 (from US$1.60 to US$3.35) and increased the tax on non-cigarette tobacco products from 70% to 95% of the wholesale price. The current study explores the change in tobacco prices in retail locations and whether the tax increase was fully passed to consumers.

Methods

An observational study of tobacco retail prices was performed in a sample of 61 convenience stores in Minnesota, North Dakota, South Dakota and Wisconsin. Six rounds of data were collected between May 2013 and January 2014. In each round, purchases were made at the same stores for the same four tobacco products (Camel Blue cigarettes, Marlboro Gold cigarettes, Grizzly Wintergreen moist smokeless tobacco and Copenhagen Wintergreen moist smokeless tobacco).

Results

For all studied tobacco products, prices in Minnesota increased significantly after the tax increase (Round 1–Round 6). After controlling for price changes in neighbouring states, the average price difference in Minnesota for the two cigarette brands increased by US$1.89 and US$1.81, which are both more than the US$1.75 tax increase. For moist smokeless, the average price difference increased by US$0.90 and US$0.94. Significant price changes were not observed in the comparison states. After the introduction of the minimum moist smokeless tax, a significantly higher proportion of Minnesota stores offered price promotions on smokeless tobacco.

Conclusions

A large tobacco tax resulted in an average retail cigarette price exceeding the tax, suggesting the industry over-shifted the cigarette tax increase to consumers in Minnesota. The findings support the known public health benefit of tobacco tax increases while highlighting the need for additional information about how, or if, tobacco companies use price promotions to blunt the impact of tax increases.

Lab experiments on cigarette warnings typically use a brief one-time exposure that is not paired with the cigarette packs smokers use every day, leaving open the question of how repeated warning exposure over several weeks may affect smokers. This proof of principle study sought to develop a new protocol for testing cigarette warnings that better reflects real-world exposure by presenting them on cigarette smokers’ own packs.

Methods

We tested a cigarette pack labelling protocol with 76 US smokers ages 18 and older. We applied graphic warnings to the front and back of smokers’ cigarette packs.

Results

Most smokers reported that at least 75% of the packs of cigarettes they smoked during the study had our warnings. Nearly all said they would participate in the study again. Using cigarette packs with the study warnings increased quit intentions (p<0.05).

Conclusions

Our findings suggest a feasible pack labelling protocol with six steps: (1) schedule appointments at brief intervals; (2) determine typical cigarette consumption; (3) ask smokers to bring a supply of cigarette packs to study appointments; (4) apply labels to smokers’ cigarette packs; (5) provide participation incentives at the end of appointments; and (6) refer smokers to cessation services at end of the study. When used in randomised controlled trials in settings with real-world message exposure over time, this protocol may help identify the true impact of warnings and thus better inform tobacco product labelling policy.

In April 2014, the Food and Drug Administration (FDA) proposed a rule to extend its tobacco regulatory authority to e-cigarettes, which have been unregulated and growing in use since their 2006–2007 US introduction. The FDA will issue a final rule based on comments and data received from researchers, tobacco companies and the public. We aimed to present data about current smokers’ awareness of and attitudes towards potential e-cigarette regulation and various policies in the USA.

Methods

We conducted a cross-sectional online e-cigarette focused survey of 519 adult current smokers in April 2014, before the FDA's proposed rule was announced. Participants were recruited from a private research panel (GFK's Knowledge Networks) designed to be representative of the US population.

Results

The majority of respondents (62.5%) did not know that e-cigarettes are unregulated by the FDA but agreed that e-cigarettes should be regulated by the FDA for safety and quality (83.5%), carry warning labels about their potential risks (86.6%) and have the same legal age of sale as other tobacco (87.7%). Support was similarly high among current e-cigarette users. Support was substantial though lower overall for policies to restrict e-cigarette indoor use (41.2%), flavouring (44.3%) and advertising (55.5%), and was negatively associated with current e-cigarette use.

Conclusions

Support for many e-cigarette regulatory policies is strong among smokers, including for policies that the FDA has recently proposed and potential future regulations. States considering indoor e-cigarette restrictions should know that a substantial number of current smokers support such regulations.

A modern advancement of university student identification cards is the ability to load the card with ‘campus cash’, converting it to a debit card that can be used to purchase goods and services at various university-affiliated merchants on-campus and off-campus. Students or, more commonly, parents can load these university debit cards with money. Policies regarding the use and management of these debit cards are institution specific. Some universities allow use of campus cash at off-campus vendors while others limit the debits cards for on-campus use only, such as dining halls and convenience stores. A prior study discovered that 42% of surveyed university students used their university debit card to purchase cigarettes.1 In addition, more than one-quarter million youth who had never smoked a cigarette used electronic cigarettes (e-cigarettes) in 2013.2

This study tests relationships between the volume of advertisements (ads; public service announcements (PSAs)) employed in state antismoking campaigns, use of different themes and stylistic features in these PSAs, and state youth smoking prevalence between 1999 and 2005.

Methods

We merged commercially available data on televised antismoking PSAs that aired between 1998 and 2004 with data on state tobacco control activity to test the relationship between the volume and content of youth-targeted and general-targeted/adult-targeted antismoking PSAs on youth smoking prevalence, controlling for other tobacco control efforts. We use content analysis and ordinary least squares (OLS) regression to assess which thematic and stylistic features employed in state antismoking PSAs are associated with reduced smoking prevalence.

Results

A 100-ad increase in the yearly volume of youth-targeted state antismoking PSAs was associated with a 0.1 percentage point decrease in state youth smoking rates in the following year. This relationship was driven by variation in state use of PSAs emphasising health consequences to self or others and anti-industry appeals. Controlling for appearances of these themes, use of graphic imagery and personal testimonials did not predict reduced smoking prevalence. Adult-targeted/general-targeted PSAs were not associated with youth smoking prevalence.

Conclusions

Youth-targeted state antitobacco PSAs that emphasise the health consequences of smoking (to oneself and others) and contain anti-industry appeals are associated with reduced youth smoking rates. Future work should avoid typologies that do not account for the co-occurrence of thematic and stylistic content in antitobacco PSAs.

Adults with mental illness in the USA suffer excess smoking-related morbidity and mortality.1 Recent studies examining trends from 2001–2005 and 2004–2011 have shown consistently higher smoking prevalence and less successful quitting among those with mental illness, across an array of diagnoses.23 However, national data may mask changes in jurisdictions such as New York City (NYC), where comprehensive tobacco control (CTC) including taxation, legislation, education and access to cessation medications has operated for a decade (see Kilgore et al for details).4

Methods

We analysed data from the NYC Community Health Survey (CHS),5 to assess whether declines in the citywide smoking prevalence between 2003 and 20124 extend to those with serious psychological distress (SPD), measured using the K6, a scale developed for population mental health assessment.6 CHS is a serial cross-sectional survey of NYC adults conducted annually...]]>

Background

Differences in carcinogen exposure from different cigarette products could contribute to differences in smoking-associated cancer incidence among Chinese compared with US smokers.

Comparing Chinese versus US smokers, daily nicotine intake and nicotine intake per cigarette smoked were found to be similar. When normalised for cigarettes per day, urine NNAL excretion was fourfold higher in US smokers, while the excretion of urine metabolites of the PAHs fluorene, phenanthrene and pyrene metabolites was 50% to fourfold higher in Chinese smokers (all, p<0.0001). Similar results were seen when NNAL and PAHs excretion was normalised for daily nicotine intake.

Conclusions

Patterns of carcinogen exposure differ, with lower exposure to TSNA and higher exposure to PAHs in Chinese compared with US smokers. These results most likely reflect country differences in cigarette tobacco blends and manufacturing processes, as well as different environmental exposures.

E-cigarettes are seen by some as offering harm reduction potential, where used effectively as smoking cessation devices. However, there is emerging international evidence of growing use among young people, amid concerns that this may increase tobacco uptake. Few UK studies examine the prevalence of e-cigarette use in non-smoking children or associations with intentions to smoke.

Methods

A cross-sectional survey of year 6 (10–11-year-old) children in Wales. Approximately 1500 children completed questions on e-cigarette use, parental and peer smoking, and intentions to smoke. Logistic regression analyses among never smoking children, adjusted for school-level clustering, examined associations of smoking norms with e-cigarette use, and of e-cigarette use with intentions to smoke tobacco within the next 2 years.

Results

Approximately 6% of year 6 children, including 5% of never smokers, reported having used an e-cigarette. By comparison to children whose parents neither smoked nor used e-cigarettes, children were most likely to have used an e-cigarette if parents used both tobacco and e-cigarettes (OR=3.40; 95% CI 1.73 to 6.69). Having used an e-cigarette was associated with intentions to smoke (OR=3.21; 95% CI 1.66 to 6.23). While few children reported that they would smoke in 2 years’ time, children who had used an e-cigarette were less likely to report that they definitely would not smoke tobacco in 2 years’ time and were more likely to say that they might.

Conclusions

E-cigarettes represent a new form of childhood experimentation with nicotine. Findings are consistent with a hypothesis that children use e-cigarettes to imitate parental and peer smoking behaviours, and that e-cigarette use is associated with weaker antismoking intentions.

Framework Convention on Tobacco Control (FCTC) Article 11 Guidelines recommend that health warning labels (HWLs) should occupy at least 50% of the package, but the tobacco industry claims that increasing the size would not lead to further benefits. This article reports the first population study to examine the impact of increasing HWL size above 50%. We tested the hypothesis that the 2009/2010 enhancement of the HWLs in Uruguay would be associated with higher levels of effectiveness.

Methods

Data were drawn from a cohort of adult smokers (≥18 years) participating in the International Tobacco Control (ITC) Uruguay Survey. The probability sample cohort was representative of adult smokers in five cities. The surveys included key indicators of HWL effectiveness. Data were collected in 2008/09 (prepolicy: wave 2) and 2010/11 (postpolicy: wave 3).

The 2009/2010 changes to HWLs in Uruguay, including a substantial increment in size, led to increases of key HWL indicators, thus supporting the conclusion that enhancing HWLs beyond minimum guideline recommendations can lead to even higher levels of effectiveness.

To estimate the direct and indirect costs of active smoking in Vietnam.

Method

A prevalence-based disease-specific cost of illness approach was utilised to calculate the costs related to five smoking-related diseases: lung cancer, cancers of the upper aerodigestive tract, chronic obstructive pulmonary disease, ischaemic heart disease and stroke. Data on healthcare came from an original survey, hospital records and official government statistics. Morbidity and mortality due to smoking combined with the average per capita income were used to calculate the indirect costs of smoking by applying the human capital approach. The smoking-attributable fraction was calculated using the adjusted relative risk values from phase II of the American Cancer Society Cancer Prevention Study (CPS-II). Costs were classified as personal, governmental and health insurance costs.

Results

The total economic cost of smoking in 2011 was estimated at 24 679.9 billion Vietnamese dong (VND), equivalent to US$1173.2 million or approximately 0.97% of the 2011 gross domestic product. The direct costs of inpatient and outpatient care reached 9896.2 billion VND (US$470.4 million) and 2567.2 billion VND (US$122.0 million), respectively. The government’s contribution to these costs was 4534.3 billion VND (US$215.5 million), which was equivalent to 5.76% of its 2011 healthcare budget. The indirect costs (productivity loss) due to morbidity and mortality were 2652.9 billion VND (US$126.1 million) and 9563.5 billion VND (US$454.6 million), respectively. These indirect costs represent about 49.5% of the total costs of smoking.

Conclusions

Tobacco consumption has large negative consequences on the Vietnamese economy.

How electronic cigarettes and similar products (e-cigarettes) are defined affects how they are regulated, particularly whether existing laws for cigarettes apply, including sales and marketing, youth access, smoke-free and taxation laws.

Methods

We examined the text of 46 bills that define e-cigarettes enacted in 40 states and characterised how e-cigarettes and similar products were defined.

Results

States enact laws creating new product categories for e-cigarettes separate from the ‘tobacco product’ category (eg, ‘alternative nicotine product,’ ‘vapour product,’ ‘electronic nicotine device’), with four states explicitly excluding e-cigarettes from ‘tobacco products.’ Twenty-eight states do not include e-cigarettes in their definitions of ‘tobacco products’ or ‘smoking,’ eight include e-cigarettes as ‘tobacco products,’ three include e-cigarettes in ‘smoking.’ Sixteen states’ definitions of e-cigarettes require nicotine, and five states pre-empt more stringent local laws. Tobacco and e-cigarette industry representatives tried to shape laws that benefit their interests.

Conclusions

Definitions separating e-cigarettes from other tobacco products are common. Similar to past ‘Trojan horse’ policies, e-cigarette policies that initially appear to restrict sales (eg, limit youth access) may actually undermine regulation if they establish local pre-emption or create definitions that divide e-cigarettes from other tobacco products. Comparable issues are raised by the European Union Tobacco Products Directive and e-cigarette regulations in other countries. Policymakers should carefully draft legislation with definitions of e-cigarettes that broadly define the products, do not require nicotine or tobacco, do not pre-empt stronger regulations and explicitly include e-cigarettes in smoke-free and taxation laws.

To examine the effect of varying levels of comprehensive tobacco control on smoking in a global context.

Methods

Using data from WHO's Reports on the Global Tobacco Epidemic, scatter plots were produced to visualise the relationship between comprehensive tobacco control policy (2008 MPOWER composite score) and change in current tobacco smoking between 2006 and 2009. Fixed-effect regression models assessed the effect of changes in each MPOWER measure on changes in current tobacco smoking between 2006 and 2009. All analyses were stratified by sex.

Results

Overall, countries with higher MPOWER composite scores experienced greater decreases in current tobacco smoking between the years 2006 and 2009. Regression analyses revealed that the M and R measures showed a negative association with current tobacco smoking over time. Current tobacco smoking decreased (1.07 percentage points for males, 1.04 percentage points for females) with each increase in score value for monitoring tobacco use (M). Also, current tobacco smoking decreased (0.95 percentage points for males, 0.41 percentage points for females) with each increase in score value for raising taxes on tobacco (R). The effect of the MPOWER measures on current tobacco smoking varied by country income status (P measure in the female analysis; p<0.05) and/or by WHO region (M, P and O measures in the male analysis; p<0.05).

Conclusions

Higher levels of MPOWER combined, as well as continued and frequent monitoring of tobacco use (M) and increasing taxation (R), were associated with a decrease in current tobacco smoking over time.

This study assessed the prevalence and determinants of e-cigarette use among persons aged ≥15 years in 27 European Union (EU) member countries during 2012.

Methods

The 2012 Eurobarometer 385 (77.1) survey was analysed for n=26 566 respondents. Knowledge, perception of harm, and determinants of e-cigarettes use were assessed, while separate regression analyses among current (n=7352) and former cigarette smokers (n=5782) were performed. National estimates of the number of e-cigarette users were also extrapolated.

Results

20.3% of current smokers, 4.7% of ex-smokers, and 1.2% of never cigarette smokers in the EU reported having ever used an e-cigarette (overall approximately 29.3 million adults). Among smokers, ever e-cigarette use was more likely among 15–24-year-olds (aOR 3.13, 95% CI 2.22 to 4.54) and 25–39-year-olds (aOR 2.00, 95% CI 1.47 to 2.78) in comparison to older smokers, and among those who smoked 6–10 cigarettes/day (aOR 1.53, 95% CI 1.10 to 2.13) or 11–20 cigarettes/day (aOR 2.07, 95% CI 1.52 to 2.81) in comparison to very light smokers (≤5 cigarettes/day). Moreover, e-cigarette use was more likely among smokers who had made a past year quit attempt (aOR 2.08, 95% CI 1.67 to 2.58). E-cigarette use among ex-smokers was associated only with the respondents’ age, with younger ex-smokers being more likely to have ever used an e-cigarette.

Conclusions

A substantial number of EU adults have ever used e-cigarettes. Ever users were more likely to be younger, current smokers, or past-year quit attempters. These findings underscore the need to evaluate the potential long term impact of e-cigarette use on consumer health, cessation and nicotine addiction and formulate a European framework for e-cigarette regulation within the revised EU Tobacco Product Directive.

The cigarette excise taxes and the price of a typical pack of cigarettes in Korea have not increased since 2005, and effective tax rate as a fraction of price and real price of cigarettes have both been falling. As smoking prevalence is higher among lower income people than among higher income people in Korea, the regressivity of cigarette excise taxes is often cited as a barrier to tobacco tax and price policy. While studies in several other high-income countries have shown that higher income individuals are less price sensitive, few studies have examined the differential impact of cigarette tax increases by income group in Korea. Most of the Korean literature has estimated the demand for cigarettes using time-series aggregate sales data or household level survey data, which record household cigarette expenditures rather than individual cigarette consumption. Studies using survey data often lack time-series variation and estimate cigarette demand using household expenditure data, while studies using time-series aggregate sales data lack cross-sectional variation.

Objective

I examine differences in the effects of cigarette price on the cigarette consumption of various income groups using individual-level cigarette consumption records from the Korea National Health and Nutrition Examination Survey (KHNNES). I also analyse the implications of cigarette taxes and price increases on the relative tax burdens of different income groups.

Design

I use pooled data from the KNHNES for the 1998–2011 period to estimate the price elasticity of cigarette consumption of four income groups. Treating cigarette consumption as a latent variable, I employ an econometric procedure that corrects for non-random sample selection, or the fact that some non-smokers might have smoked at a low enough price, and estimate the price elasticity of cigarette consumption by income group. The estimated price elasticities include the responsiveness of potential smokers as well as current smokers.

Results

Lower income Korean smokers are more responsive to changes in the price of cigarettes. While the overall price elasticity of cigarettes is estimated to be –0.425, the price elasticity of the lowest income quartile is estimated to be –0.812, whereas that of the highest income quartile is estimated to be –0.325.

Conclusions

The estimated price elasticities of different income groups imply that the cigarette tax and price increases in Korea would reduce smoking more in those with lower incomes. For a given price increase, the percentage reduction in cigarette consumption among smokers in the lowest income quartile is 2.5 times greater than among smokers in the top income quartile. The simulated tax burdens of different income groups show that the additional burden of a tax increase and the associated price rise is largely borne by higher income smokers.

Colorado QuitLine callers who smoked 16–20 cigarettes per day at enrolment and who were eligible for and agreed to receive free NRT.

Intervention

Provision of 4-week versus 8-week NRT supply; the 8-week supply was shipped in halves and required participants to request the second half (split-shipment protocol). Enrolment occurred during March 2010–February 2011, follow-up concluded in November 2011, and analysis was performed in 2012.

Overall, 1495 study participants were enrolled and 57.7% completed follow-up. Abstinence rates did not differ significantly between study conditions: 13.8% versus 12.4% in 4-week versus 8-week arms, respectively, (30-day point abstinence, non-respondents treated as smokers). NRT duration was similar in both groups, due in part to purchase of additional patches in the 4-week group. About one-third of the 8-week group requested the full 8-week supply and had higher abstinence rates. Cost per quit was lower in the 4-week (compared to 8-week) group.

Conclusions

A randomised trial did not find worse cessation outcomes among quitline users who received half the minimum recommended course of NRT, but offering the full recommended course using a split-shipment protocol may be reasonably cost-effective and supportive of NRT adherers.

To investigate the association of cigarette smoking at baseline and trajectories of dysmenorrhoea in a large sample of Australian women.

Design

A prospective cohort study.

Setting

Australian (population-based survey).

Participants

A total of 9067 young women, with at least three measures of dysmenorrhoea, randomly sampled from the national Medicare database and followed up from 2000 to 2012.

Main outcome measures

Trajectories of dysmenorrhoea.

Results

At baseline, approximately 25% reported dysmenorrhoea and 26% were current smokers. Four trajectory groups were identified for dysmenorrhoea: normative (42%), late onset (11%), recovering (33%) and chronic (14%), with the chronic group showing high probabilities of reporting dysmenorrhoea over time. Compared with never-smokers, a significantly higher odds of being in the chronic group was detected for smokers, with ORs being 1.33 (95% CI 1.05 to 1.68) for ex-smokers and 1.41 (95% CI 1.17 to 1.70) for current smokers, after adjusting for sociodemographic, lifestyle and reproductive factors. An inverse relationship was identified for earlier age of smoking initiation, with the respective ORs of 1.59 (95% CI 1.18 to 2.15), 1.50 (95% CI 1.18 to 1.90) and 1.26 (95% CI 1.03 to 1.55) for initiation of smoking ≤13, 14–15 or ≥16 years. No consistent relationship was evident between smoking behaviour and the odds of being in the other trajectory groups.

Conclusions

Smoking and early initiation of smoking are associated with increased risk of chronic dysmenorrhoea. The immediate adverse health effects of smoking provide further support for smoking prevention programme to target young women, especially teenagers.

To determine if smokers unmotivated to quit reduce usual cigarette consumption when cigarettes priced according to nicotine content are made available.

Methods

Randomised, parallel-group, trial (ACTRN12612000914864) undertaken in Wakatipu/Central Otago, New Zealand. Dependent adult daily smokers unmotivated to quit were randomly allocated to an intervention group provided with 12 weeks supply of free very low nicotine content (VLNC) cigarettes, or to a control group, who were free to purchase their usual cigarette brand over the same period. The primary outcome was change from baseline in the daily mean number of usual cigarettes smoked over the previous week, measured at 12 weeks. Secondary outcomes at 6 and 12 weeks included cigarettes smoked per week (also measured at weeks 1–6 and 9), salivary cotinine, tobacco dependence, smoking satisfaction/craving, behavioural addiction to smoking, autonomy over smoking, motivation to stop, price at which participants would purchase VLNC cigarettes, quitting and adverse events.

Results

Thirty-three smokers were randomised (17 intervention, 16 control). A NZ$15 price differential (per pack of 20) based on nicotine content led to a halving in the mean number of cigarettes smoked per day over the previous week, a reduction in tobacco dependence and an increase in quitting. Intervention participants smoked a similar total number of cigarettes (usual plus VLNC) as those in the control group, exposing them to a similar level of toxicants.

Conclusions

Smokers unmotivated to quit reduce their usual cigarette consumption (and thus nicotine exposure) when VLNC cigarettes are made available at a significantly reduced price.

Secondhand smoke (SHS) likely provides additional exposure to nicotine and toxins for smokers, but has been understudied. Our objective was to determine whether SHS exposure among smokers yields detectable differences in cotinine levels compared with unexposed smokers at the population level.

Methods

Using the US National Health and Nutrition Examination Survey (NHANES) for the years 1999–2012, we compared serum cotinine levels of 4547 current adult cigarette smokers stratified by self-reported SHS exposure sources (home and/or work) and smoking intensity. A weighted multivariable linear regression model determined the association between SHS exposure and cotinine levels among smokers.

Results

Smokers with SHS exposure at home (43.8%) had higher cotinine levels (β=0.483, p≤0.001) compared with those with no SHS exposure at home after controlling for the number of cigarettes smoked per day and number of days smoked in the previous 5 days, survey year, age, gender and education. Smokers with SHS exposure at work (20.0%) did not have significantly higher cotinine levels after adjustment. The adjusted geometric mean cotinine levels of light smokers (1–9 cigarettes per day) with no SHS exposure, exposure at work only, home only, and both home and work were 52.0, 62.7, 67.2, 74.4 ng/mL, respectively, compared with 219.4, 220.9, 255.2, 250.5 ng/mL among moderate/heavy smokers (≥10 cigarettes per day).

Conclusions

Smokers living in residences where others smoke inside the home had significantly higher cotinine levels than smokers reporting no SHS exposure, regardless of individual smoking intensity. Future research should target the role that SHS exposure may have in nicotine dependence, cessation outcomes and other health impacts among smokers.

Plain packaging (PP) for tobacco products was fully implemented in Australia on 1 December 2012 along with larger graphic health warnings. Using longitudinal data from the Australian arm of the ITC Four Country Survey, we examined attitudes to the new packs before and after implementation, predictors of attitudinal change, and the relationship between support and quitting activity.

Methods

A population-based cohort study design, with some cross-sectional analyses. Surveys of Australian smokers assessed attitudes to PP at four time points prior to implementation (from 2007 to 2012) and one post-implementation wave collected (early/mid-2013).

Results

Trend analysis showed a slight rise in opposition to PP among smokers in the waves leading up to their implementation, but no change in support. Support for PP increased significantly after implementation (28.2% pre vs 49% post), such that post-PP more smokers were supportive than opposed (49% vs 34.7%). Multivariate analysis showed support either before or after implementation was predicted by belief in greater adverse health impacts of smoking, desire to quit and lower addiction. Among those not supportive before implementation, having no clear opinion about PP (versus being opposed) prior to the changes also predicted support post-implementation. Support for PP was prospectively associated with higher levels of quitting activity.

Conclusions

Since implementation of PP along with larger warnings, support among Australian smokers has increased. Support is related to lower addiction, stronger beliefs in the negative health impacts of smoking, and higher levels of quitting activity.

Smoking usually develops in adolescence and is patterned by socioeconomic position (SEP). We examined whether early adolescent smoking development and associations with SEP have changed over time in a population with well-developed tobacco control policies. We additionally investigated the relative importance of socioeconomic inequalities at different stages of smoking development.

Methods

An annual UK rotating panel survey including data from 5122 adolescents (51% male) aged 11–15 years between 1994 and 2008. Rates of smoking initiation, progression to occasional smoking (experimentation), progression to daily smoking (escalation), and quitting were examined using discrete-time event history analysis.

Results

Initiation, experimentation and escalation rates declined over the study period while quitting rates increased. Decreases in initiation were concentrated among older adolescents and decreases in escalation among those who spent a year or two as occasional smokers. Socioeconomic disadvantage was associated with higher rates of initiation and escalation, with similar findings across SEP measures. Inequalities in initiation were stronger at younger ages. There was less evidence of associations between SEP and quitting or experimentation. Inequalities in escalation remained constant over time, while inequalities in initiation widened before narrowing. Further modelling suggested that differential initiation rates contributed more to inequalities in daily smoking at age 15 than did differential escalation.

Conclusions

Increasing tobacco control in the UK is associated with reduced uptake and more quitting in early adolescence, but socioeconomic inequalities remain. Interventions should focus on reducing inequalities in initiation among early adolescents.

The sensory belief that ‘light/low tar’ cigarettes are smoother can also influence the belief that ‘light/low tar’ cigarettes are less harmful. However, the ‘light’ concept is one of several factors influencing beliefs. No studies have examined the impact of the sensory belief about one's own brand of cigarettes on perceptions of harm.

Objective

The current study examines whether a smoker's sensory belief that their brand is smoother is associated with the belief that their brand is less harmful and whether sensory beliefs mediate the relation between smoking a ‘light/low tar’ cigarette and relative perceptions of harm among smokers in China.

Methods

Data are from 5209 smokers who were recruited using a stratified multistage sampling design and participated in wave 3 of the International Tobacco Control (ITC) China Survey, a face-to-face survey of adult smokers and non-smokers in seven cities.

Results

Smokers who agreed that their brand of cigarettes was smoother were significantly more likely to say that their brand of cigarettes was less harmful (p<0.001, OR=6.86, 95% CI 5.64 to 8.33). Mediational analyses using the bootstrapping procedure indicated that both the direct effect of ‘light/low tar’ cigarette smokers on the belief that their cigarettes are less harmful (b=0.24, bootstrapped bias corrected 95% CI 0.13 to 0.34, p<0.001) and the indirect effect via their belief that their cigarettes are smoother were significant (b=0.32, bootstrapped bias-corrected 95% CI 0.28 to 0.37, p<0.001), suggesting that the mediation was partial.

Conclusions

These results demonstrate the importance of implementing tobacco control policies that address the impact that cigarette design and marketing can have in capitalising on the smoker's natural associations between smoother sensations and lowered perceptions of harm.

Neighbourhood retailing of tobacco products has been implicated in affecting smoking prevalence rates. Long-term smoking usually begins in adolescence and tobacco control strategies have often focused on regulating ‘child spaces’, such as areas in proximity to schools. This cross-sectional study examines the association between adolescent smoking behaviour and tobacco retail outlet density around home and school environments in Scotland.

Methods

Data detailing the geographic location of every outlet registered to sell tobacco products in Scotland were acquired from the Scottish Tobacco Retailers Register and used to create a retail outlet density measure for every postcode. This measure was joined to individual responses of the Scottish Schools Adolescent Lifestyle and Substance Use Survey (n=20 446). Using logistic regression models, we explored the association between the density of retailers, around both home and school address, and smoking behaviours.

Results

Those living in the areas of highest density of retailers around the home environment had 53% higher odds of reporting having ever smoked (95% CI 1.27 to 1.85, p<0.001) and 47% higher odds of reporting current smoking (95% CI 1.13 to 1.91 p<0.01). Conversely, those attending schools in areas of highest retail density had lower odds of having ever smoked (OR 0.66, 95% CI 0.50 to 0.86 p<0.01) and lower odds of current smoking (OR 0.75, 95% CI 0.59 to 0.95, p<0.05).

Conclusions

The density of tobacco retail outlets in residential neighbourhoods is associated with increased odds of both ever smoked and current smoking among adolescents in Scotland. Policymakers may be advised to focus on reducing the overall density of tobacco outlets, rather than concentrating on ‘child spaces’.

Across the Americas, Chile has the highest prevalence of adult and youth smoking (40.6% and 39.2%, respectively).12 The WHO's Framework Convention on Tobacco Control recommends prohibiting direct and indirect tobacco advertising, promotion and sponsorship (TAPS), including portrayals of tobacco in films.3 The tobacco industry has long used films to promote its products.34 Evidence from numerous countries consistently demonstrates that exposure to tobacco use in films promotes youth smoking, which provides the rationale for policy development in this area.34

In May 2011, Chile introduced legislation to ban smoking in enclosed public spaces. From May 2011 to January 2013, Chilean lawmakers discussed amending this legislation to include a ban of all forms of indirect TAPS. The tobacco and entertainment industries lobbied against this legislation, and the TAPS provisions were weakened when they passed in January 2013....]]>

To assess the extent to which multiple tobacco product use among adolescents and young adults falls outside current Food and Drug Administration (FDA) regulatory authority.

Methods

We conducted a web-based survey of 1596 16–26-year-olds to assess use of 11 types of tobacco products. We ascertained current (past 30 days) tobacco product use among 927 respondents who ever used tobacco. Combustible tobacco products included cigarettes, cigars (little filtered, cigarillos, premium) and hookah; non-combustible tobacco products included chew, dip, dissolvables, e-cigarettes, snuff and snus. We then fitted an ordinal logistic regression model to assess demographic and behavioural associations with higher levels of current tobacco product use (single, dual and multiple product use).

Results

Among 448 current tobacco users, 54% were single product users, 25% dual users and 21% multiple users. The largest single use category was cigarettes (49%), followed by hookah (23%), little filtered cigars (17%) and e-cigarettes (5%). Most dual and multiple product users smoked cigarettes, along with little filtered cigars, hookah and e-cigarettes. Forty-six per cent of current single, 84% of dual and 85% of multiple tobacco product users consumed a tobacco product outside FDA regulatory authority. In multivariable analysis, the adjusted risk of multiple tobacco use was higher for males, first use of a non-combustible tobacco product, high sensation seeking respondents and declined for each additional year of age that tobacco initiation was delayed.

Conclusions

Nearly half of current adolescent and young adult tobacco users in this study engaged in dual and multiple tobacco product use; the majority of them used products that fall outside current FDA regulatory authority. This study supports FDA deeming of these products and their incorporation into the national media campaign to address youth tobacco use.

Outdoor smoking bans are recommended1 but some are contentious.2–4 Reasons for outdoor smoking bans include providing a supportive environment for ex-smokers, and, reducing the risk of: acute health effects from secondhand smoke; modelling smoking to young people; and litter and fire risk. Conversely, one argument given against outdoor smoking bans is the low and transient long-term health risk. All Australian jurisdictions have, or intend to have, legislation for smoke-free outdoor areas but the legislation is diverse in terms of which outdoor areas are included and who is responsible for implementation and regulation (ie, State or Local Government). On 31 May 2012, the South Australian Government amended the Tobacco Products Regulation Act 20075 to include smoking bans in prescribed (outdoor) public transport areas (bus stops, tram stops, railway stations, taxi ranks and airports) and within 10 m of children's outdoor playground equipment....]]>2014-10-31T09:01:12-07:00info:doi/10.1136/tobaccocontrol-2014-051825hwp:master-id:tobaccocontrol;tobaccocontrol-2014-051825BMJ Publishing Group Ltd2014-10-31Lettershttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2014-051830v1?rss=1
Objective

While flavoured cigarettes were prohibited in the USA in 2009, flavoured little cigars and cigarillos (LCCs) remain on the market. We describe the evolving strategies used by tobacco companies to encourage uptake of flavoured LCCs and industry research findings on consumer perceptions of flavoured LCC products.

Methods

Analysis of internal tobacco industry documents was triangulated with data from tobacco advertisement archives, national newspapers, trade press and the internet.

Results

Flavoured LCC products were associated with young and inexperienced tobacco users, women and African-Americans. Internal industry studies confirmed that menthol and candy-like flavours (eg, vanilla and cherry) increased LCC appeal to starters by masking the heavy cigar taste, reducing throat irritation and making LCC smoke easier to inhale. To appeal to new users, manufacturers also reduced the size of cigars to make them more cigarette-like, introduced filters and flavoured filter tips, emphasised mildness and ease of draw in advertising, and featured actors using little cigars in television commercials. RJ Reynolds tried to capitalise on the popularity of menthol cigarettes among African–Americans and marketed a menthol little cigar to African–Americans.

Conclusions

Tobacco companies engaged in a calculated effort to blur the line between LCCs to increase the appeal to cigarette smokers, and the use of flavours facilitated these efforts. Bans on flavoured cigarettes should be expanded to include flavoured LCCs, and tobacco use prevention initiatives should include LCCs.

Smoke-free policies not only reduce harm to non-smokers, they may also reduce harm to smokers by decreasing the number of cigarettes smoked and increasing the likelihood of a successful quit attempt. However, little is known about the impact of exposure to smoking on patios on smoking behaviour.

Design and participants

Smokers from the Ontario Tobacco Survey, a longitudinal population representative cohort of smokers (2005–2011). There were 3460 current smokers who had completed one to six follow-ups and were asked at each follow-up whether or not they had been exposed to smoking on patios in the month.

Main outcome measures

Generalised estimating equations and survival analysis were used to examine the association between exposure to patio smoking and smoking behaviour changes (making a quit attempt and time to relapse after a quit attempt), controlling for potential confounders.

Results

Smokers who were exposed to smoking on patios (adjusted incident rate ratio (aIRR) = 0.89; 95% CI 0.81 to 0.97) or had been to a patio (aIRR = 0.86; 95% CI 0.74 to 0.99) were less likely to have made a quit attempt than smokers who had not visited a patio. Smokers who were exposed to smoking on patios were more likely to relapse (adjusted HR=2.40; 95% CI 1.07 to 5.40)) after making a quit attempt than those who visited a patio but were not exposed to smoking.

Conclusions

Exposure to smoking on patios of a bar or restaurant is associated with a lower likelihood of success in a quit attempt. Instituting smoke-free patio regulations may help smokers avoid relapse after quitting.

This paper aimed to estimate the effect of tobacco taxes on total mortality and cause-specific mortality in the 50 States plus the District of Columbia, USA, over the period 1970–2005 as well as the net effect on deaths averted in 2010.

Methods

We used a fixed effects panel regression to measure the impact of changes in total tobacco taxes on total and cause-specific mortality rates over the period 1970–2005, using a 5-year lag structure between changes in tobacco taxes and mortality rates. The estimates were used to determine the number of deaths averted in the year 2010 by tobacco tax increases over the period 1970–2005.

Results

Descriptive results showed that nominal total tobacco tax increased from US$0.18 in 1970 to US$1.24 in 2005, which after adjusting to 2005 US$, corresponds to an increase in real total tobacco tax from US$ 0.89 in 1970 to US$ 1.24 in 2005. We found that increases in total tobacco tax were beneficial, with a $1 increase in total tobacco tax decreasing overall mortality rate by 8.0%. Based on these results, we estimated a net saving of 53 300 lives in 2010 due to the tobacco tax changes over the period 1970–2005.

China is home to the greatest number of smokers as well as the greatest number of smoking-related deaths. An active and growing market of cigarettes marketed as ‘light’ or ‘low tar’ may keep health-concerned smokers from quitting, wrongly believing that such brands are less harmful.

Objective

This study sought to observe changes in cigarette design characteristics and reported tar, nicotine and carbon monoxide (TNCO) levels in a sample of cigarette brands obtained in seven Chinese cities from 2009 to 2012.

Methods

Cigarettes were purchased and shipped to Roswell Park Cancer Institute, where 91 pairs of packs were selected for physical cigarette design characteristic testing and recording of TNCO values. Data analysis was conducted using SPSS, and was initially characterised using descriptive statistics, correlations and generalised estimating equations to observe changes in brand varieties over time.

Findings

Reported TNCO values on packs saw mean tar, nicotine and CO levels decrease from 2009 to 2012 by 7.9%, 4.5% and 6.0%, respectively. Ventilation was the only cigarette design feature that significantly changed over time (p<0.001), with an increase of 31.7%. Significant predictors of tar and CO yield overall were ventilation and per-cigarette tobacco weight, while for nicotine tobacco moisture was also an independent predictor of yield.

Conclusions

The use of ventilation to decrease TNCO emissions is misleading smokers to believe that they are smoking a ‘light/low’ tar cigarette that is healthier, and is potentially forestalling the quitting behaviours that would begin to reduce the health burden of tobacco in China, and so should be prohibited.

Many alternative tobacco products (ATPs), such as hookahs, have grown in popularity and use beyond their locale of origin and are therefore becoming a significant global public health concern. This article provides an overview of an under-reported and understudied ATP, dokha, which is smoked in a midwakh pipe. It describes the state of tobacco control in the Arabian Gulf region where midwakh smoking appears to be most common, the history of midwakh and dokha use, and what is known about midwakh smoking from the published literature. On the basis of the stark lack of data on midwakh use, we suggest priority areas to focus future research. Preliminary data and observations from health providers and the public health sector suggest that midwakh smoking may pose challenges to the tobacco control efforts in the Arabian Gulf region. If it is emerging as a new ATP outside this region, there could be a significant impact on tobacco control strategies globally.]]>2014-10-23T09:00:35-07:00info:doi/10.1136/tobaccocontrol-2013-051530hwp:master-id:tobaccocontrol;tobaccocontrol-2013-051530BMJ Publishing Group Ltd2014-10-23Special communicationshttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2014-051804v1?rss=1
Background

Metals of primary health concern can accumulate in the tobacco plant and contribute to smokers’ exposures to carcinogens, a significant cause of the millions of smoking-related deaths in China each year. These exposures are due to the smoker's addiction to nicotine.

Objective

This study sought to explore toxic heavy metal and nicotine concentrations in the tobacco of Chinese cigarette brands purchased in 2009 and 2012, as well as its regional variation.

Methods

Cigarette packs for this study were purchased from seven Chinese cities in 2009 and 2012, and 91 pairs of cigarettes were matched based on UPC for comparison. Ten cigarette sticks were randomly selected from each pack and tested using polarised energy dispersive X-ray fluorescence (XRF) for arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni) and lead (Pb) concentrations. Nicotine analysis was conducted following Coresta's Recommended Method N°62. Data analysis was conducted using SPSS, encompassing descriptive statistics, correlations and generalised estimating equations to observe changes in brand varieties overtime.

Findings

On average, from 2009 to 2012, As, Cd, Cr and Pb concentrations have decreased in Chinese tobacco. Of the seven cities where the cigarette brands were purchased, only four cities showed significant differences of the selected metals from 2009 to 2012. However, there was no significant change in the tobacco nicotine content from 2009 to 2012.

Conclusions

Tobacco in Chinese cigarettes purchased in seven geographically disbursed cities contains consistently high levels of metals, including carcinogens like Cd. One source may be the improper use of fertilisers. These numbers should be monitored more carefully and regulated by health officials.

The goal of this study was to summarise the websites of electronic cigarette (e-cigarette) manufacturers in China and describe how they market their products.

Methods

From March to April 2013, we used two search keywords ‘electronic cigarette’ (Dian Zi Xiang Yan in Chinese) and ‘manufacturer’ (Sheng Chan Chang Jia in Chinese) to search e-cigarette manufacturers in China on Alibaba, an internet-based e-commerce business that covers business-to-business online marketplaces, retail and payment platforms, shopping search engine and data-centric cloud computing services. A total of 18 websites of 12 e-cigarette manufacturers in China were analysed by using a coding guide which includes 14 marketing claims.

Results

Health-related benefits were claimed most frequently (89%), followed by the claims of no secondhand smoke (SHS) exposure (78%), and utility for smoking cessation (67%). A wide variety of flavours, celebrity endorsements and e-cigarettes specifically for women were presented. None of the websites had any age restriction on access, references to government regulation or lawsuits. Instruction on how to use e-cigarettes was on 17% of the websites.

Conclusions

Better regulation of e-cigarette marketing messages on manufacturers’ websites is needed in China. The frequent claims of health benefits, smoking cessation, strategies appealing to youth and women are concerning, especially targeting women. Regulators should prohibit marketing claims of health benefits, no SHS exposure and value for smoking cessation in China until health-related, quality and safety issues have been adequately addressed. To avoid e-cigarette use for initiation to nicotine addiction, messages targeting youth and women should be prohibited.

Little is known about the relationship between national tobacco control policies and implementation of private home smoking bans.

Objective

To determine the relationship between the Tobacco Control Scale (TCS), a score measuring national-level strength of tobacco control policies, and the prevalence of in-home smoking bans and beliefs on other tobacco control policies, among the Member States (MS) of the European Union (EU) that participated in the Pricing Policy And Control of Tobacco in Europe (PPACTE) project.

Methods

A face-to-face representative survey, based on 18 056 individuals aged ≥15 years, from 18 European countries—including 16 EU MS—was conducted in 2010. Multilevel logistic regression models were fit to examine the relationship between the TCS score and in-home smoking ban prevalence and beliefs that other policy approaches are useful.

Results

In 2010, the TCS scores ranged from 32 in Austria and Greece to 77 in England. The TCS score correlated with the prevalence of in-home smoking bans (rsp=0.65). A 10-unit increase in the TCS score significantly increased the odds of in-home smoking ban (OR=1.33; 95% CI 1.01 to 1.76). The odds of believing that providing cessation services (OR=1.21), raising prices (OR=1.01) and extending bans is useful (OR=0.93) were not significant.

Conclusions

Government tobacco control policies are positively related to the individual-level tobacco policy of having an in-home smoking ban.

Two products indigenous to the Indian subcontinent and popular among South Asians globally - paan and paan masala - are inconsistently categorised as tobacco by researchers, clinicians, program planners and policymakers. This article calls for a universally standard classification of these smokeless carcinogenic products as tobacco products and thus, subject to the same public health and clinical protections applied to other forms of tobacco. This recommendation is guided by scientific evidence strongly indicating the common presence of tobacco in paan and paan masala. Inclusion of these two products in population-level surveillance, clinical screening, as well as public health program planning and policy interventions may have considerable impact on preventing and reducing tobacco-related disparities among South Asians around the world.]]>2014-10-21T09:01:35-07:00info:doi/10.1136/tobaccocontrol-2014-051700hwp:master-id:tobaccocontrol;tobaccocontrol-2014-051700BMJ Publishing Group Ltd2014-10-21Special communicationshttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2014-051922v1?rss=1
Background

This study assessed the role of cigarette design and marketing characteristics in initial smoking, cigarette brand choice and the perception of reduced harm of cigarette brands among adults in the European Union in 2012.

Methods

Data were from the Eurobarometer 385 (V.77.1) survey conducted in 2012 (n=26 566). Multivariate logistic regression was used to assess associations between cigarette design/marketing features with aspects of initial smoking (among current and former smokers), cigarette brand choice and perception of reduced harm of cigarette brands (among current smokers; p<0.05).

Results

Respondents aged ≥55 years had lower OR than 15–24-year-olds of reporting initial smoking because of the presence of menthol flavour (adjusted OR (AOR)=0.42; 95% CI 0.24 to 0.72) or a specific sweet, fruity or spicy flavour (AOR=0.38; 95% CI 0.20 to 0.73). Females had higher OR than males of reporting initial smoking because of the presence of menthol flavour (AOR=2.89; 95% CI 2.07 to 4.02). Furthermore, female smokers were more likely to choose a cigarette brand based on specific tastes such as menthol or spicy, fruity or sweet flavours (AOR=1.33; 95% CI 1.14 to 1.56), or on the levels of tar, nicotine and carbon monoxide (AOR=1.30; 95% CI 1.11 to 1.52). Characteristics such as light-coloured packaging, the shape and size of cigarettes and the pack, the use of terms in the brand name such as ‘silver’ or ‘blue’ or descriptors such as ‘natural’ or ‘organic’ were all associated with perceptions of reduced harm among specific demographic groups.

Conclusions

These findings call for a stronger regulation of tobacco ingredients, packaging features and other marketing strategies that may increase the attractiveness of tobacco products or promote perceptions of harm reduction.

The goal of this study was to assess the healthcare costs attributable to secondhand smoke (SHS) exposure among non-smoking adults (age ≥19) in rural China.

Methods

We analysed data from the 2011 National Rural Household Survey which was conducted among adults in five provinces and one municipality in China (N=12 397). Respondents reported their smoking status, health conditions and healthcare expenditures. Relative risks were obtained from published sources. Healthcare costs included annual outpatient and inpatient hospitalisation expenditures for five SHS-related diseases: asthma, breast cancer (female only), heart disease, lung cancer and tuberculosis. SHS-attributable healthcare costs were estimated using a prevalence-based annual cost approach.

Findings

The total healthcare costs of SHS exposure in rural China amounted to $1.2 billion in 2011, including $559 million for outpatient visits and $612.4 million for inpatient hospitalisations. The healthcare costs for women and men were $877.1 million and $294.3 million, respectively. Heart disease was the most costly condition for both women ($701.7 million) and men ($180.6 million). The total healthcare costs of SHS exposure in rural China accounted to 0.3% of China's national healthcare expenditures in 2011. Over one-fifth of the total healthcare costs of SHS exposure in rural China were paid by health insurance. The out-of-pocket expenditures per person accounted for almost half (47%) of their daily income.

Conclusions

The adverse health effects of SHS exposure result in a large economic burden in China. Tobacco control policies that reduce SHS exposure could have an impact on reducing healthcare costs in China.

Using data on fine particulate matter less than 2.5 μm (PM2.5) concentrations in smoking and non-smoking homes in Scotland to estimate the mass of PM2.5 inhaled by different age groups.

Methods

Data from four linked studies, with real-time measurements of PM2.5 in homes, were combined with data on typical breathing rates and time-activity patterns. Monte Carlo modelling was used to estimate daily PM2.5 intake, the percentage of total PM2.5 inhaled within the home environment and the percentage reduction in daily intake that could be achieved by switching to a smoke-free home.

Results

Median (IQR) PM2.5 concentrations from 93 smoking homes were 31 (10–111) μg/m3 and 3 (2–6.5) μg/m3 for the 17 non-smoking homes. Non-smokers living with smokers typically have average PM2.5 exposure levels more than three times higher than the WHO guidance for annual exposure to PM2.5 (10 μg/m3).

Conclusions

Fine particulate pollution in Scottish homes where smoking is permitted is approximately 10 times higher than in non-smoking homes. Taken over a lifetime many non-smokers living with a smoker inhale a similar mass of PM2.5 as a non-smoker living in a heavily polluted city such as Beijing. Most non-smokers living in smoking households would experience reductions of over 70% in their daily inhaled PM2.5 intake if their home became smoke-free. The reduction is likely to be greatest for the very young and for older members of the population because they typically spend more time at home.

To review qualitative research and synthesise findings about socioeconomically disadvantaged and socially marginalised adolescents and young adults in mature tobacco control contexts.

Data sources

Searches of PubMed and MEDLINE, additional purposive searches in Google Scholar, PsycINFO, grey literature, specialist journals and reference lists for English language articles published after 2000. Search terms were qualitative, youth or adolescent or young adult, smoking/tobacco and vulnerable populations or disadvantage or socioeconomic inequality. The most recent update of the search was undertaken in January 2014.

Study selection

Twenty articles, reporting on 17 studies, from 902 initial records were included. Inclusion criteria were: qualitative study undertaken in a country in the final stage of the tobacco epidemic and with comprehensive tobacco control measures in place, participants were youth who were socioeconomically disadvantaged or members of an identified subgroup with higher smoking prevalence and/or resided in a geographical area of low socioeconomic status. The target age range was 10–24.

Data extraction

Data were independently extracted by one author, summarised and reviewed, compared and re-reviewed at multiple time points.

Data synthesis

The majority of studies were from the UK, with the remainder from the USA, Australia and New Zealand. The review used a thematic analysis approach, and started with an open question: ‘what does qualitative research tell us about disadvantaged young people and smoking?’ The synthesis provides insights into the social context of smoking for marginalised and disadvantaged young people, group affiliation and identity, the role of smoking in social capital and sources of cigarettes.

Conclusions

Surprisingly few qualitative studies focused exclusively on smoking and disadvantaged young people were found. Future qualitative studies on the intersection between specific psychosocial characteristics associated with disadvantage and increased smoking risk would be of use to inform approaches to reduce socioeconomic differentials in smoking prevalence.

Smoke-free policies aiming to improve quality of indoor air and significantly reduce exposure to secondhand smoke in the hospitality industry are faced with strong opposition from the tobacco industry and hospitality venue owners claiming that they lead to reductions of revenues. The objective of our study was to examine the impact of a recently introduced smoke-free legislation on the revenues of the hospitality industry in Cyprus.

Methods

Anonymous information on revenues was obtained from the Cyprus government value added tax office for the entire hospitality industry in Cyprus including hotels, bars, restaurants and cafeterias between 2005 and 2011. Panel data methodology was used to examine the effect of a smoke-free legislation, on tourism, businesses’ revenues adjusting for gross domestic product, inflation, unemployment rate, tourists’ arrivals, seasonal variation and the economic crisis.

Results

Our study showed that the implementation of the smoke-free policy did not have negative effects on the hospitality industry profitability.

Conclusions

We conclude that even in regions with relatively high smoking rates, pro-smoking societal attitudes and weak social norms against tobacco control, and even during periods of economic crisis, smoke-free legislation does not impact negatively on hospitality industry revenues and if anything may lead to a small positive increase.

The China Tobacco Museum in Shanghai is the largest in China, consisting of seven pavilions of tobacco-related exhibits. A focus group and previous survey data revealed that the museum conveys messages that make tobacco use appealing. Of the pavilions, three were found to contain blatant misinformation about tobacco and tobacco consumption. We argue that the China Tobacco Museum is a platform for tobacco promotion, a form of tobacco advertising, promotion and sponsorship, and thus contravenes the FCTC.]]>2014-09-30T09:00:33-07:00info:doi/10.1136/tobaccocontrol-2014-051633hwp:master-id:tobaccocontrol;tobaccocontrol-2014-051633BMJ Publishing Group Ltd2014-09-30Special communicationshttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2014-051765v1?rss=1
Background

Recent studies have suggested that about 1 in 5 smokers report switching brands per year. However, these studies only report switching between brands. The current study estimated the rates of switching both within and between brand families and examining factors associated with brand and brand style switching.

Methods

Data for this analysis are from the International Tobacco Control 2006–2011 US adult smoker cohort survey waves 5–8 (N=3248). A switch between brands was defined as reporting two different cigarette brand names for two successive waves, while switching within brand was defined as reporting the same brand name, but a different brand style. Repeated measures regression was used to determine factors associated with both switch types.

Results

A total of 1475 participants reported at least two successive waves of data with complete information on brand name and style. Overall switching increased from 44.9% in 2007–2008 to 58.4% in 2010–2011. Switching between brand names increased from 16% to 29%, while switches within the same brand name to a different style ranged from 29% to 33%. Between-brand switching was associated with younger age, lower income, non-white racial group and use of a discount brand, whereas, within-brand switching was associated with younger age and the use of a premium brand cigarette.

Conclusions

Nearly half of smokers in the USA switched their cigarette brand or brand style within a year. Switching between brands may be more price motivated, while switching within brands may be motivated by price and other brand characteristics such as product length.

In countries where there are large disparities in smoking with persistent high rates among disadvantaged groups, there is a need to ensure that stop smoking services (SSS) reach such smokers. The primary aim of this study was to evaluate the effectiveness of a mobile, drop-in, community-based SSS in reaching more disadvantaged smokers, particularly those from routine and manual (RM) occupation groups, than standard services; secondary aims were to evaluate effectiveness in reaching those who had not previously accessed SSS, triggering unplanned quit behaviour, helping people quit and cost-effectiveness.

Methods

Following a 4-week pilot period, a mobile drop-in SSS was delivered across various public locations in Nottingham City, UK for 6 months, offering behavioural and pharmacological support via one-to-one consultations with trained cessation advisors. Detailed demographic and smoking behaviour data were collected from all clients accessing the mobile SSS, and Nottingham's standard SSS for comparison.

Results

Compared with smokers accessing the standard SSS (n=1856), mobile SSS smokers (n=811) were significantly more likely to be from the RM group (33.3% vs 27.2%, p=0.002), and to be first-time SSS users (67.8% vs 59.3%, p<0.001). Nearly 1 in 10 smokers setting a quit date through the mobile SSS had no prior quit intentions. The cost per smoker setting a quit date for the mobile SSS was only slightly higher than the standard SSS (£224 vs £202).

Conclusions

A mobile drop-in SSS is an effective way of reaching more disadvantaged smokers from RM occupations, as well as those who have not previously accessed standard SSS and those without prior quit intentions.

Mental health units have usually been exempted from complete smoke-free policies. The aim of this study was to compare the self-reported level of exposure to secondhand smoke (SHS) of patients and staff in psychiatric units to objective measures, and examine preference for different types of smoking bans.

Methods

Cross-sectional survey about ban preferences and self-reported exposure to SHS by means of a self-administered questionnaire administered to patients and staff from 65 inpatient psychiatric units in Catalonia (95.5% of all units). We measured air concentrations of particulate matter ≤2.5 μm (PM2.5 in µg/m3) as a marker of SHS in these units.

Results

600 patients and 575 professionals completed the questionnaire. 78.7% of them were objectively exposed to SHS (PM2.5>10 μm/m3) but 56.9% of patients and 33.6% of staff believed they were not exposed at all and 41.6% of patients and 28.4% of staff believed the environment was not at all unhealthy. Nurses had a higher smoking prevalence than psychiatrists (35.8% vs 17.2%; p<0.001), and nurses had a higher perception of being moderately highly exposed to SHS (40.3% vs 26.2%; p<0.001). PM2.5 levels were significantly different depending on the type of smoking ban implemented but unrelated to the perception of SHS levels by both patients and staff. Only 29.3% of staff and 14.1% of patients strongly supported total smoking bans.

Conclusions

Patients and staff have substantial misperceptions about the extent of their exposure to SHS and low awareness about the harmful environment in which they stay/work. This might have an influence on the preference for less restrictive smoke-free bans. It is particularly noteworthy that less that one-third of mental health staff supported smoke-free units, suggesting an urgent need for further education about the harmful health effects of SHS.

Hookahs are increasingly being used in the USA and elsewhere. Despite the popularity of hookah bars, there is a paucity of research assessing the health effects of hookah smoke, and although New York City (NYC) bans indoor tobacco smoking, hookah lounges claim that they only use herbal products without tobacco. This study investigated levels of multiple indices of indoor air pollution in hookah bars in NYC.

These results demonstrate that despite the ban on smoking tobacco products, at the very least, some NYC hookah bars are serving tobacco-based hookahs, and have elevated concentrations of indoor air pollutants that may present a health threat to visitors and employees. Therefore, there is an urgent need for better air quality monitoring in such establishments and policies to combat this emerging public health threat.

Although higher taxation of tobacco products is considered the most cost-effective tobacco control policy, its negative impact on low-income groups is one of the arguments used against it.

Objective

To investigate the impact of current excise taxes and the increases of excise taxes on tobacco and household expenditures by expenditure tertiles, and examine who pays excise taxes in general.

Method

Impacts of excise taxes on cigarettes are examined with a budgetary approach. We first estimate the price elasticity of cigarettes by expenditure tertiles using data from the 2003 Turkish Household Expenditure Survey, the most recent data set covering detailed tobacco product information relevant to our analysis. We then conduct a number of simulation analyses by increasing the excise taxes per pack of cigarettes and examine the impacts of these increases on household expenditures. Finally, as excise tax increases, we predict the total excise tax paid by households in different expenditure tertiles and compare the concentration curve of excise tax spending with the Lorenz curve showing the cumulative share of total household expenditures by expenditure tertiles. We estimate the progressivity coefficient that measures the area between the Lorenz and concentration curves.

Results

The low-income group is found to be the most sensitive to tax and price increases. It spends a relatively higher share of the household expenditure on cigarettes compared with higher income groups. However, the results suggest a different outcome as excise tax increases; the share of household expenditures spent on cigarettes declines for all household tertiles but a significant reduction occurs on the lowest expenditure tertile, suggesting that increases in excise taxes are progressive. Furthermore, the highest expenditure tertile pays the highest excise tax among expenditure tertiles, and their share in total excise revenue increases as the excise tax per pack of cigarettes increases.

Conclusions

The poor smoking households benefit the most from increases in excise taxes; from a budgetary perspective, as they reduce their smoking consumption significantly, the share of their excise payment in total household expenditures declines. From a health perspective, they are likely to have more health benefits as their consumption reduces. Government revenues are also predicted to increase with increased excise taxes, and the government can allocate a part of these revenue increases on implementing and enforcing other tobacco control measures including cessation support and smoke-free environments.

Recently, a tobacco product, Chaini Khaini, identified as snus appeared in India. The product marketing emphasises its discreet nature and explicitly claims safety by referring to the existing evidence on Swedish snus. We analysed tobacco-specific nitrosamines and nicotine in 12 samples of Chaini Khaini purchased in 2013 at open markets in India.

Methods

Samples were purchased twice: in March 2013 from Mumbai and in November 2013 from Mumbai and Ahmedabad. Chemical constituents were measured by our routine validated methods.

Results

Levels of carcinogenic nitrosamines NNN, NNK and NNAL averaged 22.9 (±4.9), 2.6 (±1.0) and 3.1 (±1.5) µg/g tobacco (wet weight), respectively. The levels of NAB, which is normally present in trace levels in tobacco products, ranged from 3.9 to 12.9 µg/g tobacco. Total nicotine levels in all samples averaged 10.0 mg/g tobacco and unprotonated nicotine accounted for an average 95.4% of the total nicotine content.

Conclusions

Chaini Khaini, which is labelled as snus and is marketed as a safe alternative to other tobacco products contains very high levels of carcinogenic nitrosamines and biologically available nicotine. Interventions are urgently needed to educate current and potential consumers of this product.

Daily smokers were recruited and interviewed on locked psychiatric units at three smoke-free San Francisco Bay Area hospitals. Intent to quit smoking was not required to participate and 73% of eligible smokers enrolled. Analyses focused on 816 participants (49% female) randomised to interventions providing counselling tailored to readiness to quit with availability of NRT posthospitalisation. Logistic regressions tested demographic, smoking and psychiatric factors predictive of NRT requests, quit attempts and abstinence 1-week postdischarge.

Results

Participants averaged 17 (SD=10) cigarettes/day for an average of 19 (SD=14) years. Most (88%) requested study-provided NRT (74% right at discharge). Participants preparing to quit and those with more severe psychiatric symptoms were more likely to request NRT at discharge (p<0.01). Those with more severe psychiatric symptoms also were more likely to request NRT refill, as were older participants (p<0.05). Participants who requested NRT at discharge were more likely to make a 24 h quit attempt and self-report abstinence at the 1-week follow-up (54% quit attempt, 14% abstinent) than participants who did not (25% quit attempt, 4% abstinent) (p<0.05).

Conclusions

The great demand for NRT and the association between NRT use with quit attempts and abstinence at 1-week posthospitalisation supports adoption of tobacco treatment in acute psychiatric settings.

The tobacco industry often relies on the assertion that smokers make ‘informed adult choices’. We tested this argument by exploring how young adults initiate smoking.

Methods

Fifteen in-depth interviews with young adults who had started smoking since turning 18, the legal age of adulthood and tobacco purchase in New Zealand. We undertook a thematic analysis of the interview transcripts.

Results

Although participants had a general awareness that smoking is harmful and knew some specific risks, they rarely saw these as personally relevant when they started smoking, and few had made a deliberate decision to smoke. Participants’ poor understanding of addiction meant most regarded smoking as a short-term phase they could stop at will. Initiation contexts discouraged the exercise of informed choice, as smoking onset often occurred when participants were influenced by alcohol or located in socially-pressured situations that fostered spur of the moment decisions.

Conclusions

Young adults’ ability to exercise ‘informed choice’ at the time of smoking uptake is constrained by cognitive and contextual factors. We propose an updated informed choice framework that recognises these factors; we outline environmental changes that could make default adoption of smoking less common while promoting more ‘informed choices’.

Reducing the nicotine content of cigarettes is a potential regulatory strategy that may enable cessation. The present study investigated the effect of nicotine exposure while smoking very low nicotine content (VLNC) cigarettes on cessation outcomes. The roles of possible sources of nicotine were also explored, including the VLNC cigarette and co-use of cigarettes with normal nicotine content.

Methods

A secondary data analysis of two analogous randomised trials of treatment seeking, adult daily smokers (n=112) who were instructed to smoke VLNC cigarettes for 6 weeks and then make a quit attempt. Controlling for baseline demographic and smoking features, the association between reductions in nicotine exposure during the 6-week trial, assessed by urinary total cotinine and biomarker-confirmed smoking abstinence 1 month later, was tested. Subsequent analyses controlled for the effects of the frequency of VLNC and normal nicotine content cigarette use and the nicotine yield of the VLNC cigarette (0.05 vs 0.09 mg).

Results

Greater reductions in nicotine exposure while smoking VLNC cigarettes predicted abstinence independent of individual differences in baseline smoking, cotinine, dependence, gender and study. Nicotine reduction was largest among individuals who were assigned to smoke a VLNC cigarette with lower nicotine yield and who smoked fewer normal nicotine content and VLNC cigarettes.

Conclusions

In the context of nicotine regulations and corresponding research, factors that undermine nicotine reduction must be addressed, including the availability and use of cigarettes with normal nicotine content and not sufficiently reducing the nicotine yield of cigarettes. Maximising nicotine reduction may facilitate smoking cessation.

This study examined whether adaptation of existing antitobacco television and radio advertisements (ads) from high-income countries is a viable tobacco control strategy for Africa.

Methods

1078 male and female adult smokers and non-smokers, aged 18–40 years, from major and smaller urban locations in Kenya, Nigeria and Senegal, were recruited into groups using locally appropriate convenience sampling methods and stratified by smoking status, gender, age and socioeconomic status. Eligibility criteria included age, smoking status and literacy. Each participant rated five radio and five TV antismoking ads on five-point scales, which were later aggregated into measures of perceived effectiveness, potential behaviour change and antitobacco industry sentiment/support for government actions.

Results

For radio ads across all three countries, two health harms-focused ads—Coughing Child followed by Suffering—had the highest odds of a positive rating on the Perceived Effectiveness measure among smokers and non-smokers. For television ads, the strong graphic ad Baby Alive tended to be rated most positively across the majority of measures by all subgroups.

Conclusions

This first systematic study of tobacco control advertisements in Africa is consistent with findings from other countries, suggesting that graphic health-harms ads developed and used in other countries could also be effective in African countries. This implies that adaptation would be a successful approach in Africa, where scarce resources for tobacco control communications can be focused on advertising dissemination, saving programmes from the cost, time and technical expertise required for development of new materials.

Despite declines in overall US cigarette consumption, the menthol cigarette market share has increased in recent years. Advertising contributes to menthol initiation and use, but little has been done to characterise menthol cigarette advertising outside of the point of sale.

Methods

Two full-service advertising firms were used to develop a library of menthol cigarette advertisements (ads) over a 9-month period (June 2012–February 2013) in the USA. The volume of ads, media channel (direct mail, print, online, email), estimated spend and households reached was summarised overall and by brand in 2013. Direct mail, email and print ads were coded for content and the target audience of print publications was examined.

Results

Over the study period, 205 menthol cigarette ads were identified with estimated expenditures exceeding US$31 million, with 70% spent on direct mail ads. Over 90% of ads promoted Camel, Marlboro and Newport menthol cigarettes. A majority (87%) of direct mail ads contained coupons or other incentives known to appeal to price-sensitive customers. Only two brands’ print ads appeared during this period: Newport ads focused on themes of sociability and sexuality, and were placed in magazines targeting African-Americans and younger consumers; American Spirit print ads were placed in general interest magazines and predominantly stressed the ‘natural’ aspects of their brand.

Discussion

The tobacco industry continues to spend millions of dollars promoting menthol cigarettes through channels that preferentially target vulnerable subgroups, such as African-Americans and younger consumers. Public health campaigns to educate and combat the influence of menthol advertising are needed.

The military has had a long pro-tobacco tradition. Despite official policy discouraging smoking, tobacco still is widely seen as part of military culture. While active smoking has presented a particular challenge for the military, in recent years there also has been increasing concern with secondhand smoke. This is especially true in closed environments and submarines may be deployed for months at a time. The current case study describes the successful implementation by the Navy of a comprehensive ban on smoking aboard submarines.

Methods

The authors searched documents on the internet, popular media, military-based news outlets and the scientific literature. We also conducted interviews with Navy officers who were instrumental in policy implementation.

Findings

Data demonstrating substantial exposure of non-smokers to tobacco smoke aboard submarines had major impact on successful adoption of the policy. A systematic and extended roll out of the ban included establishing a working group, soliciting input and active engagement from submarine personnel, and offering cessation assistance. Support was enlisted from Chief Petty Officers who could have been strongly opposed but who became strong proponents. Fewer problems were encountered than had been expected. In contrast to a previous unsuccessful attempt by a Navy captain to ban smoking on his ship, the ban was adopted without apparent tobacco industry interference.

Conclusions

Lessons learned included the importance of strong empirical support, effective framing of the issue, setting a realistic timeline, soliciting support from key personnel and providing appropriate resources. These lessons have implications for those considering further tobacco policy changes in the military and elsewhere.

Tobacco excise taxes are known to be effective in reducing smoking at the population level, but less research has examined how individual smokers respond to changes in tax policy. We ask whether price elasticities for individual smokers, derived from simulated demand curves obtained with a cigarette purchase task (CPT), can predict changes in smoking after a tax increase.

Method

Smokers (N=357) were recruited from four New Zealand cities and interviewed before and after a 10% tobacco excise tax increase.

Results

Simulated demand curves from the CPT were curvilinear and well described by an exponential model. Smokers reported significant reductions in cigarettes/day and addiction scores at Wave 2 (n=226). Local elasticities derived from the demand curves significantly predicted decreases in cigarettes/day after controlling for covariates.

Conclusions

Elasticities from simulated demand curves can predict decreases in consumption for individual smokers after an excise tax increase. Understanding individual differences in tobacco demand curves may help to predict how different groups of smokers will respond to price increases.

Despite marketing prohibitions, tobacco company marketing expenditures in the USA have continued to grow with tobacco companies shifting focus towards point-of-sale-marketing and direct marketing to consumers through the mail and on the web. The purpose of this observational study was to investigate the content of direct marketing sent in response to registrations on select industry websites.

Methods

An analysis of 659 tobacco company direct mail marketing pieces received between July 2011 and June 2012 was conducted. Mailings were coded for type and value of tobacco coupons, type of tobacco products promoted with coupons and number and type of giveaways offered.

Results

The most common type of mailing was tobacco coupon distribution; 86.5% of the mailings contained at least one coupon. Mailings with coupons had an average estimated coupon value of $4.17. The total coupon value of each mailing varied by the type of coupon offer and product promoted. The Camel and Marlboro coupon mailings heavily promoted snus, with over half of Camel coupon mailings (60.9%) and nearly half (44.8%) of Marlboro coupon mailings promoting snus alone. In addition, 47.9% of Marlboro coupon mailings and 11.4% of Camel mailings promoted snus alongside cigarettes.

Discussion

Tobacco companies use direct mail marketing to communicate with consumers and provide valuable tobacco coupons. More research is needed to understand the content of these mailings and how they are used by tobacco consumers in order to develop effective policy solutions.

Waterpipe tobacco smoking (WTS), a traditional tobacco consumption practice in the Middle East, is gaining popularity worldwide. Estimates of population-level interest in WTS over time are not documented. We assessed the popularity of WTS using World Wide Web search query results across four English-speaking countries.

Methods

We analysed trends in Google search queries related to WTS, comparing these trends with those for electronic cigarettes between 2004 and 2013 in Australia, Canada, the UK and the USA. Weekly search volumes were reported as percentages relative to the week with the highest volume of searches.

Results

Web-based searches for WTS have increased steadily since 2004 in all four countries. Search volume for WTS was higher than for e-cigarettes in three of the four nations, with the highest volume in the USA. Online searches were primarily targeted at WTS products for home use, followed by searches for WTS cafés/lounges.

Conclusions

Online demand for information on WTS-related products and venues is large and increasing. Given the rise in WTS popularity, increasing evidence of exposure-related harms, and relatively lax government regulation, WTS is a serious public health concern and could reach epidemic levels in Western societies.

To compare predictive values of small-for-gestational-age (SGA) by different measures for secondhand smoke (SHS) exposure during pregnancy and to develop and validate a prediction model for SGA using SHS exposure along with sociodemographic and pregnancy factors.

Methods

We compared the predictability of different measures of SHS exposure during pregnancy for SGA among 545 Chinese pregnant women, and then used the optimal SHS measure along with other clinically available factors to develop and validate a prediction model for SGA. We fit logistic regression models to predict SGA by single measures of SHS exposure (self-report, serum cotinine and CYP2A6*4) and different combinations (self-report+cotinine, cotinine+CYP2A6*4, self-report+CYP2A6*4 and self-report+cotinine+CYP2A6*4).

Results

We found that self-reported SHS exposure alone predicted SGA (area under the receiver operating characteristic curve or area under the receiver operating curve (AUROC), 0.578) better than the other two single measures (cotinine, 0.547; CYP2A6*4, 0.529) or as accurately as combined SHS measures (0.545–0.584). The final prediction model that contained self-reported SHS exposure, prepregnancy body mass index, gestational weight gain velocity during the second and third trimesters, gestational diabetes, gestational hypertension and the third-trimester biparietal diameter Z-score could predict SGA fairly accurately (AUROC, 0.698).

Conclusions

Self-reported SHS exposure at peribirth performs better in predicting SGA than a single measure of serum cotinine at the same time, although repeated biochemical cotinine assessments throughout pregnancy may be optimal. Our simple prediction model is fairly accurate and can be potentially used in routine prenatal care.

The 1990s state litigation that resulted in the tobacco industry's initial document disclosure obligations fully expired in 2010. These obligations have been extended and enhanced until 2021 through a federal lawsuit against the tobacco industry over violations of the Racketeer Influenced Corrupt Organizations Act (RICO). In this special communication, we summarise and explain the new legal framework and enhanced document disclosure obligations of the major US tobacco companies. We describe the events leading up to these new requirements, including the tobacco companies’ failed attempt to close the Minnesota Tobacco Document Depository, the release of 100 000 documents onto the companies’ document websites discovered to have been publicly available at the Minnesota Tobacco Document Depository but not online, and the addition of over 2300 documents to those websites, which are also now publicly available at Minnesota after being secured for years in a separate, non-public storage room at the Minnesota Tobacco Document Depository. We also detail the document indexing enhancements and redesign of the University of California, San Francisco's Legacy Tobacco Documents Library website, made possible by the RICO litigation, and which is anticipated to be released in September 2014. Last, we highlight the public health community's continued opportunity to expose the US tobacco industry's efforts to undermine public health through these new search enhancements and improved document accessibility and due to the continuously growing document collection until at least 2021.]]>2014-07-21T23:37:51-07:00info:doi/10.1136/tobaccocontrol-2014-051749hwp:master-id:tobaccocontrol;tobaccocontrol-2014-051749BMJ Publishing Group Ltd2014-07-21Special communicationshttp://tobaccocontrol.bmj.com/cgi/content/short/tobaccocontrol-2013-051454v1?rss=1
Aim

To examine the effects of tobacco control television advertisements with positive and negative emotional content on adult smoking prevalence and cigarette consumption.

After adjusting for cigarette costliness, other tobacco control policies and individual characteristics, we found that a 400-point increase in positive emotive GRPs was associated with 7% lower odds of smoking (odds ratio (OR) 0.93, 95% CI 0.87 to 0.98) 1 month later and a similar increase in negative emotive GRPs was significantly associated with 4% lower odds of smoking (OR 0.96, 95% CI 0.92 to 0.999) 2 months later. An increase in negative emotive GRPs from 0 to 400 was also associated with a significant 3.3% (95% CI 1.1 to 5.6) decrease in average cigarette consumption. There was no evidence that the association between positive emotive GRPs and the outcomes differed depending on the intensity of negative emotive GRPs (and vice versa).

Conclusions

This is the first study to explore the effects of campaigns with different types of emotive content on adult smoking prevalence and consumption. It suggests that both types of campaign (positive and negative) are effective in reducing smoking prevalence, whereas consumption among smokers was only affected by campaigns evoking negative emotions.

Exposure to e-cigarette communications (eg, advertisements, news and entertainment media, and interpersonal discussion) may influence support for smoke-free or vape-free policies. This study examined the sociodemographic correlates of self-reported exposure to e-cigarette communications and their relationships with support for restricting vaping and smoking in public venues.

Method

Online survey data was collected from a representative sample of US adults (n=1449) between October and December 2013 (mean age=50 years, 51% female, 8% African-American, 10% Hispanic, 6% other races) and weighted to match the US adult population. We fitted multiple regression models, adjusting for demographic variables, to examine associations between support for policies to restrict vaping and smoking in public venues and self-reported frequency of exposure to e-cigarette communications in the preceding month. We fitted separate models to assess associations between policy support and frequency of exposures weighted by whether each category of e-cigarette communications was perceived as positive or negative.

Results

Higher self-reported exposure to advertising (B=–0.022, p=0.006), other media (B=–0.022, p=0.043) and interpersonal discussion (B=–0.071, p<0.0005) perceived as positive were associated with lower support for vaping restrictions, adjusting for covariates. Exposure to e-cigarette communications was associated with lower support for smoking restrictions in bivariate analyses but was not significant after adjusting for covariates.

Conclusions

Further research is needed to assess whether messages portraying e-cigarettes as a way to circumvent smoking restrictions from advertisements and other media are influencing public support for vape-free policies. These findings provide empirical evidence to inform the policy debate over regulating specific e-cigarette advertising claims.

Secondhand smoke (SHS) is a leading preventable cause of illness, disability and mortality. There is a lack of quantitative analyses on socioeconomic disparities in SHS; especially, it is not known how socioeconomic disparities have changed in the past two decades in the USA.

Objectives

To examine socioeconomic disparities and long-term temporal trends in SHS exposure among US never-smoking adults aged ≥20 years.

Methods

15 376 participants from the National Health and Nutrition Examination Survey (NHANES) 1999–2010 were included in the analysis of socioeconomic disparities; additional 8195 participants from NHANES III 1988–1994 were included in the temporal trend analysis. SHS exposure was assessed using self-reported exposure in the home and workplace as well as using serum cotinine concentrations ≥0.05 ng/mL. Individual socioeconomic status (SES) was assessed using poverty-to-income ratio.

Results

During the period 1999–2010, 6% and 14% of participants reported SHS exposure in the home and workplace, respectively; 40% had serum cotinine-indicated SHS exposure. Individual SES was strongly associated with SHS exposure in a dose–response fashion; participants in the lowest SES group were 2–3 times more likely to be exposed to SHS compared with those in the highest SES group. During the period 1988–2010, the prevalence declined over 60% for the three types of SHS exposure. However, for cotinine-indicated exposure, the magnitudes of the declines were smaller for lower SES groups compared with higher SES groups, leading to widening socioeconomic disparities in SHS exposure.

Conclusions

SHS exposure is still widespread among US never-smoking adults, and socioeconomic disparities for cotinine-indicated exposure have substantially increased in the past two decades.

Smoking is the largest preventable cause of death in the UK and imposes a huge economic burden on society. Both the prevalence and extent of smoking are significantly higher among people with mental disorders than among the general population.

Aims

To estimate the economic costs of the health effects of cigarette smoking among people with mental disorders in the UK from a societal perspective.

Methods

This study uses the WHO's economics of tobacco toolkit to assess the costs of the health effects of cigarette smoking among people with mental disorders in 2009/10 in the UK. Based on the cost of illness approach, direct healthcare costs, indirect morbidity costs and indirect mortality costs due to smoking-related diseases were calculated to estimate the avoidable economic burden of smoking in people with mental disorders.

Results

The estimated economic cost of smoking in people with mental disorders was £2.34 billion in 2009/10 in the UK, of which, about £719 million (31% of the total cost) was spent on treating diseases caused by smoking. Productivity losses due to smoking-related diseases were about £823 million (35%) for work-related absenteeism and £797 million (34%) was associated with premature mortality.

Conclusions

Smoking in people with mental disorders in the UK imposes significant economic costs. The development and implementation of smoking cessation interventions in this group should therefore be a high economic and clinical priority.

To examine social gradients in tobacco use in Argentina and Uruguay, using newly available directly comparable data sets.

Methods

Secondary analysis of Global Adult Tobacco Survey data from Argentina (N=6645) and Uruguay (N=5581). Social gradients in current tobacco use, exposure to secondhand smoke, and cessation attempt were examined with sex-stratified and age-adjusted logistic regression.

Results

Among men, there is evidence of higher odds of being a current smoker among respondents with lower levels of education, but the association is only statistically significant for respondents with less than primary education in Uruguay (OR=2.15, 95% CI 1.22 to 3.77). Similarly, women with lower levels of education have higher odds of being a current smoker in Uruguay. The association between education and exposure to secondhand smoke is broadly similar for both sexes in both countries, with generally higher odds among groups with low education, though the relationship is only statistically significant among men in Uruguay (OR=1.77, 95% CI 1.08 to 2.92). In both countries, respondents with lower levels of education in general have higher odds of having attempted to quit smoking in the past year, although these associations did not attain statistical significance.

Conclusions

Social gradients in tobacco use, exposure to secondhand smoke and cessation attempts are broadly similar in both countries. Efforts to evaluate the long-term effects of tobacco control efforts in these countries should monitor how policies affect national averages, and the social gradients that are embedded in aggregate data.

To understand the competition between and among tobacco companies and health groups that led to graphical health warning labels (GHWL) on all tobacco products in India.

Methods

Analysis of internal tobacco industry documents in the Legacy Tobacco Document Library, documents obtained through India's Right to Information Act, and news reports.

Results

Implementation of GHWLs in India reflects a complex interplay between the government and the cigarette and bidi industries, who have shared as well as conflicting interests. Joint lobbying by national-level tobacco companies (that are foreign subsidiaries of multinationals) and local producers of other forms of tobacco blocked GHWLs for decades and delayed the implementation of effective GHWLs after they were mandated in 2007. Tobacco control activists used public interest lawsuits and the Right to Information Act to win government implementation of GHWLs on cigarette, bidi and smokeless tobacco packs in May 2009 and rotating GHWLs in December 2011.

Conclusions

GHWLs in India illustrate how the presence of bidis and cigarettes in the same market creates a complex regulatory environment. The government imposing tobacco control on multinational cigarette companies led to the enforcement of regulation on local forms of tobacco. As other developing countries with high rates of alternate forms of tobacco use establish and enforce GHWL laws, the tobacco control advocacy community can use pressure on the multinational cigarette industry as an indirect tool to force implementation of regulations on other forms of tobacco.

To review smoking policies of major international airports, to compare these policies with corresponding incountry tobacco control legislation and to identify areas of improvement for advancing smoke-free policy in airports.

Methods

We reviewed smoking policies of 34 major international airports in five world regions, and collected data on current national and subnational legislation on smoke-free indoor places in the corresponding airport locations. We then compared airport smoking policies with local legislation. Additionally, we collected anecdotal information concerning smoking rules and practices in specific airports from an online traveller website.

Results

We found that 52.9% of the airports reviewed had indoor smoking rooms or smoking areas; smoking policy was unknown or unstated for two airports. 55.9% of the airports were located in countries where national legislation allowed designated smoking rooms and areas, while 35.3% were in smoke-free countries. Subnational legislation restricted smoking in 60% of the airport locations, while 40% were smoke-free. 71.4% of the airport locations had subnational legislation that allowed smoke-free laws to be more stringent than at the national level, but only half of these places had enacted such laws.

Conclusions

Despite the increasing presence of smoke-free places and legal capacity to enact stricter legislation at the local level, airports represent a public and occupational space that is often overlooked in national or subnational smoke-free policies. Secondhand smoke exposure in airports can be reduced among travellers and workers by implementing and enforcing smoke-free policies in airports. Additionally, existing information on smoke-free legislation lacks consistent terminology and definitions, which are needed to inform future tobacco control policy within airports and in the law.

A variety of smoking cessation aids are available; however, the majority of smokers quit unaided. We know little of the differences between users and non-users of cessation support.

Methods

A cross-sectional study based on the Danish Health Examination Survey (DANHES) conducted in 2007–2008. In all, 6445 persons reporting quitting successfully within the last 5 years were included in analyses. Users and non-users of cessation aid (medical or behavioural support) were compared with regards to age, education, years smoked, tobacco amount, tobacco type and smoking-related disease using logistic regression analysis.

Results

Quitting unaided was reported by 63%. Adjusted analyses showed that men were more likely to quit unaided than women, and younger compared with older were more likely to quit unaided (eg, OR among women age 45–59 versus age 14–29 were 0.18, 95% CI 0.12 to 0.20). Additionally, those who had smoked for 15 years or more also had lower odds of quitting unaided. Smoking 15 or more grams of tobacco daily was inversely associated with quitting unaided (eg, OR among men were 0.38, 95% CI 0.31 to 0.46).

Conclusions

Quitting smoking without the use of formalised aid was the most common cessation approach. Quitting unaided was more likely among men, younger age groups, those with a shorter history of smoking and those who were light smokers. These results indicate that awareness of unaided cessation in general and to those for whom it is especially relevant should be increased. This could lead to a more efficient use of resources for cessation support.

Cigarette smoking causes many chronic diseases that are costly and result in frequent hospitalisation. Hospital-initiated smoking cessation interventions increase the likelihood that patients will become smoke-free. We modelled the cost-effectiveness of the Ottawa Model for Smoking Cessation (OMSC), an intervention that includes in-hospital counselling, pharmacotherapy and posthospital follow-up, compared to usual care among smokers hospitalised with acute myocardial infarction (AMI), unstable angina (UA), heart failure (HF), and chronic obstructive pulmonary disease (COPD).

Methods

We completed a cost-effectiveness analysis based on a decision-analytic model to assess smokers hospitalised in Ontario, Canada for AMI, UA, HF, and COPD, their risk of continuing to smoke and the effects of quitting on re-hospitalisation and mortality over a 1-year period. We calculated short-term and long-term cost-effectiveness ratios. Our primary outcome was 1-year cost per quality-adjusted life year (QALY) gained.

Results

From the hospital payer's perspective, delivery of the OMSC can be considered cost effective with 1-year cost per QALY gained of $C1386, and lifetime cost per QALY gained of $C68. In the first year, we calculated that provision of the OMSC to 15 326 smokers would generate 4689 quitters, and would prevent 116 rehospitalisations, 923 hospital days, and 119 deaths. Results were robust within numerous sensitivity analyses.

Discussion

The OMSC appears to be cost-effective from the hospital payer perspective. Important consideration is the relatively low intervention cost compared to the reduction in costs related to readmissions for illnesses associated with continued smoking.

Use previously secret tobacco industry documents to assess tobacco companies’ routine claims of trade secret protection for information on cigarette ingredients, additives and construction made to regulatory agencies, as well as the companies’ refusal to publicly disclose this information.

Methods

We analysed previously secret tobacco industry documents available at (http://legacy.library.ucsf.edu) to identify 100 examples of seven major tobacco companies’ reverse engineering of their competitors’ brands between 1937 and 2001.

Results

These reverse engineering reports contain detailed data for 142 different measurements for at least two companies, including physical parameters of the cigarettes, tobacco types, humectants, additives, flavourings, and smoke constituents of competitors’ cigarettes. These 100 documents were distributed to 564 employees, including top managers in domestic and foreign offices across multiple departments, including executive leadership, research and design, product development, marketing and legal. These documents reported new competitors’ products, measured ingredient changes over time, and informed companies’ decisions regarding ingredients in their own products.

Conclusions

Because cigarette companies routinely analyse their competitors’ cigarettes in great detail, this information is neither secret nor commercially valuable and, thus, does not meet the legal definition of a ‘trade secret.’ This information is only being kept ‘secret’ from the people consuming cigarettes and the scientific community. Public agencies should release this detailed information because it would provide valuable information about how ingredients affect addictiveness and toxicity, and would help the public health community and consumers better understand the impact of cigarette design on human health.

Telephone-based smoking cessation services (quitlines) offering counselling for smoking cessation without nicotine replacement therapy may be important components of tobacco control efforts in low and middle income countries, but evaluations in such resource-limited settings are lacking. We aimed to evaluate the usage, effectiveness and cost of the Thailand National Quitline (TNQ).

Methods

Analysis of retrospective data for callers to the TNQ between 2009 and 2012 and a follow-up survey in 1161 randomly selected callers.

Results

Between 2009 and 2012 there were 116 862 callers to the TNQ; 36 927 received counselling and at least one follow-up call. Compared with smokers in the general population, callers were younger, more highly educated, more likely to be students, and more likely to smoke cigarettes rather than roll-your-own tobacco. Continuous abstinence rates at 1, 3 and 6 months after calling were 49.9%, 38.0% and 33.1%. The predicted rate at 12 months was 19.54% (95% CI 14.55 to 26.24). Average cost per completed counselling was $31 and the average cost per quitter was $253. Assuming all (and two-thirds) TNQ callers who succeed in quitting would have failed to quit without the assistance of the TNQ, cumulative life years saved (LYS) for the 4-year period were 57 238 (36 733) giving a cost per LYS of $32 (50) (about 7.93 LYS per quitter) and an estimated return on investment over 4 years of 9.01 (5.78).

Conclusions

A low-cost quitline without nicotine replacement therapy is a promising model for smoking cessation services and likely to offer good value for money in Thailand.

Passive exposure to combustible cigarette use has been shown to act as a cue to increase smoking urge. Given the resemblance of e-cigarettes and other electronic nicotine delivery systems (ENDS) to combustible cigarettes, we examined whether these devices could also act as a cue to increase smoking desire and urges in those passively exposed.

Methods

Young adult daily smokers (age 18–35 years; N=60) completed subjective ratings before and after exposure to a study confederate drinking bottled water (control cue) and then smoking either a combustible or e-cigarette (active cue). Smoking desire and urge ratings were measured with visual analogue scale items for desire for a regular and an e-cigarette and the Brief Questionnaire of Smoking Urges.

Results

Passive exposure to both the e-cigarette and combustible cigarette cue significantly increased observers’ ratings of desire and urge to smoke a regular cigarette (all ps<0.05). Exposure to the e-cigarette cue but not the regular cigarette cue also increased desire to smoke an e-cigarette (p<0.01).

Conclusions

The results provide the first evidence in a controlled setting that electronic cigarette exposure may evoke smoking urges in young adult daily smokers. With replication, these findings may have relevance for ENDS regulation and policy.

In 2011, the Netherlands implemented a national policy that ensured that health insurance companies reimbursed behavioural counselling for smoking cessation or the combination of behavioural counselling with pharmacological therapy.

Objective

To examine the real-world impact of a national reimbursement policy and accompanying media attention on use of cessation treatment and on smoking cessation.

Methods

We used a four-wave longitudinal survey among 2763 adult smokers that started in September 2010 and was repeated at approximately 3 month intervals until June 2011. Two survey waves were conducted before the implementation of the policy and two survey waves after.

Findings

There were significant increases in quit attempts (among moderate-to-heavy smokers) and in quit success (among all smokers) following the implementation of the reimbursement policy and the media attention. Use of behavioural counselling did not increase, while use of pharmacological therapy without behavioural counselling (unreimbursed treatment) increased among moderate-to-heavy smokers. Attention to media about the reimbursement was significantly associated with more quit attempts and more quit success. Awareness of the policy was significantly associated with more use of reimbursed treatment among all smokers, while attention to the media coverage was only significantly associated with more use of reimbursed treatment among moderate-to-heavy smokers. Awareness/attention variables were not significantly associated with use of unreimbursed treatment.

Conclusions

It seems that a national reimbursement policy for smoking cessation treatment that is accompanied by media attention can increase cessation. Our findings suggest that this increase can (partly) be ascribed to the media attention that accompanied the policy implementation.

Spending on cigarettes may deprive households of other items like food. The goal of this study was to examine the prevalence of and factors associated with this smoking-induced deprivation among adult smokers in China.

Methods

The data came from waves 1–3 of the International Tobacco Control (ITC) China Survey, conducted from 2006 to 2009 among urban adults aged 18 years or older in China. We focus on the samples of current smokers from six cities (N=7981). Smoking-induced deprivation was measured with the survey question, "In the last six months, have you spent money on cigarettes that you knew would be better spent on household essentials like food?" We examined whether sociodemographic factors, smoking intensity and price paid per pack of cigarettes were associated with smoking-induced deprivation using generalised estimating equations modelling.

Findings

7.3% of smokers reported smoking-induced deprivation due to purchasing cigarettes. Low-income and middle-income smokers were more likely to have smoking-induced deprivation compared with high-income smokers (adjusted OR (AOR)=2.06, 95% CI 1.32 to 2.31; AOR=1.44, 95% CI 1.10 to 1.69); smokers living in Shenyang (AOR=1.68, 95% CI 1.25 to 2.24) and Yinchuan (AOR=2.50, 95% CI 1.89 to 3.32) were more likely to have smoking-induced deprivation compared with smokers living in Beijing. Retired smokers were less likely to have smoking-induced deprivation compared with employed smokers (AOR=0.67, 95% CI 0.52 to 0.87). There was no statistically significant relationship between smoking intensity, price paid per pack of cigarettes and smoking-induced deprivation.

Conclusions

Our findings indicate that certain groups of smokers in China acknowledge spending money on cigarettes that could be better spent on household essentials. Tobacco control policies that reduce smoking in China may improve household living standards by reducing smoking-induced deprivation.

A wide range of electronic cigarettes (e-cigarettes) are now on the market. We studied e-cigarette awareness and use, determinants and sources of e-cigarettes, the e-liquids used in them and exposure to e-cigarette advertisements among adolescents in Finland. Among smokers, we studied the association of e-cigarette use and interest in smoking cessation.

Method

Data were obtained from a national survey of 12–18-year-old Finnish adolescents in 2013 (N=3535, response rate 38%). Descriptive statistics and logistic regression analysis were used.

Results

Of the respondents, 85.3% knew what e-cigarettes were; 17.4% had tried them. E-liquids with nicotine were used most often (65.7%); also those who had never tried conventional cigarettes had used them. Of e-cigarette ever users, 8.3% had never tried smoking. Parents’ high level of education, being in employment, and intact family protected against children's e-cigarette use. In the final model, daily smoking (OR 41.35; 95% CI 25.2 to 67.8), snus use (2.96; 2.4–4.0), waterpipe use (2.21; 1.6–3.0), children's vocational education (2.06; 1.4–3.1) and poor school performance (1.92; 1.4–3.0) were associated with e-cigarette experimentation. Those smokers with most experience of e-cigarettes were least likely to consider smoking cessation.

Conclusions

Awareness and experimentation with e-cigarettes are high among adolescents, especially in older age groups and boys. Nicotine e-liquids are easy to acquire for youth. Having similar risk factors, e-cigarette use seems to follow the model of conventional smoking initiation. Among adolescent smokers, use of e-cigarettes does not clearly relate to interest in smoking cessation. Preventive policies are needed to protect the youth.

To date there is limited published evidence on the efficacy of tobacco control mass media campaigns in China. This study aimed to evaluate the impact of a mass media campaign ‘Giving Cigarettes is Giving Harm’ (GCGH) on Chinese smokers’ knowledge of smoking-related harms and attitudes towards cigarette gifts.

Methods

Population-based, representative data were analysed from a longitudinal cohort of 3709 adult smokers who participated in the International Tobacco Control (ITC) China Survey conducted in six Chinese cities before and after the campaign. Logistic regression models were estimated to examine associations between campaign exposure and attitudes towards cigarette gifts measured postcampaign. Poisson regression models were estimated to assess the effects of campaign exposure on postcampaign knowledge, adjusting for precampaign knowledge.

Findings

Fourteen percent (n=335) of participants recalled the campaign within the cities where the GCGH campaign was implemented. Participants in the intervention cities who recalled the campaign were more likely to disagree that cigarettes are good gifts (71% vs 58%, p<0.01) and had greater levels of campaign-targeted knowledge than those who did not recall the campaign (mean=1.97 vs 1.62, p<0.01). Disagreeing that cigarettes are good gifts was higher in intervention cities than in control cities. Changes in campaign-targeted knowledge were similar in both cities, perhaps due to a secular trend, low campaign recall or contamination issues.

Conclusions

These findings suggest that the GCGH campaign increased knowledge of smoking harms, which could promote downstream cessation. This study provides evidence to support future campaign development to effectively fight the tobacco epidemic in China.

Adolescents represent the next generation and have the greatest amount to gain from the tobacco endgame. They will provide the future momentum to achieve the tobacco endgame, thus it is important that their views on interventions are monitored. We examined support among 14–15-year-old New Zealanders for tobacco endgame goals and measures, and trends in this support from 2009 to 2012.

Methods

This study used data from an annual survey of over 25 000 Year 10 students (14–15 year olds) undertaken by Action on Smoking and Health New Zealand. We assessed support for five tobacco control goals and measures: living in a smoke-free country; having fewer tobacco retail outlets; not selling tobacco in 10 years’ time; implementing outdoor smoking bans; and raising the price of tobacco.

Results

Support for living in a smoke-free country was 59%, while support for a ban on all tobacco sales in 10 years’ time was 57% in the most recent survey year. Most respondents supported each of the tobacco control measures and gave strongest support to having fewer places where tobacco could be sold (71% in 2012). Support for the other two tobacco control measures in the most recent year ranged from 59% to 64% and had increased over time, in most cases significantly. Support was strongest among non-smokers and declined as participants’ smoking frequency increased.

Conclusions

Young people support New Zealand's smoke-free goal and interventions that could help achieve it; this evidence should galvanise policy action, which remains out of step with public opinion.

In 2011, New York City (NYC) parks and beaches became smoke-free. There is currently little research evaluating the impact of such laws on smoking behaviour at the population level.

Methods

We used an interrupted time-series study design to analyse data from the New York State Adult Tobacco Survey to assess the law's impact using the rest of New York State as a comparison. Trends in how frequently respondents noticed people smoking in parks and beaches were analysed between the third quarter of 2009 and the fourth quarter of 2012, comparing NYC to the rest of the state.

Results

The trend in the frequency of NYC residents noticing people smoking in local parks and beaches decreased significantly over the six quarters after the law took effect. There was no comparable decline among residents in the rest of the state. An increase in the number of respondents who never noticed people smoking in NYC contributed to this decline.

Conclusions

These results are consistent with previous studies and provide population-level evidence that suggest the law has reduced smoking in parks and on beaches.

Following the passage of the Family Smoking Prevention and Tobacco Control Act in 2009, flavoured cigarettes, including clove cigarettes, were banned based on the rationale that such cigarettes appealed to youth. However, the ban on characterising flavours was not extended to cigars.

Methods

This study reviewed industry documents from Kretek International, the parent company behind Djarum clove cigars, to document the changes in their marketing and production strategies following the flavour ban on cigarettes. To assess sales trends following the ban, data for clove cigar sales in the USA from 2009 to 2012 were analysed using Nielsen's Convenience Track retail scanner database. Additionally, data on tobacco imports to the USA from Indonesia were obtained from the USDA Foreign Agricultural Service’s Global Agricultural Trade System for the years 2008–2012.

Results

In anticipation of Food and Drug Administration's (FDA) flavour ban on cigarettes and recognising the regulatory advantages of cigars, Kretek International began developing Djarum clove cigars in 2007. Immediately following the flavour ban, sales of this product increased by more than 1400% between 2009 and 2012. During this same period, tobacco imports to the USA from Indonesia, a leader in clove tobacco production, shifted from cigarettes to almost exclusively cigars.

Conclusions

Kretek International, like other tobacco manufacturers, manipulated its products following the Family Smoking Prevention and Tobacco Control Act as a way to capitalise on regulatory loopholes and replace its now banned clove cigarettes. As a result, consumption of the company's Djarum clove cigars increased exponentially in recent years.

To assess secondhand smoke (SHS) exposure in Thai international airports using a fine particulate indicator, particulate matter ≤2.5 μm (PM2.5), and to compare with 2012 exposure findings in international airports in the USA.

Methods

Smoking rooms in the four largest international airports that serve the most travellers and with the most operating designated smoking rooms (DSRs) were monitored using PM2.5 monitoring equipment following an approved research protocol for assessing fine particle pollution from tobacco smoke. Monitoring was conducted inside and just outside DSRs and throughout the airport terminals in all four airports. Altogether 104 samples were taken to assess SHS exposure in four airports. Simultaneous samples were taken multiple times in a total of 11 DSRs available for sampling in the research period.

Results

Levels of PM2.5 in DSRs were extremely high in all four airports and were more dangerous inside DSRs than in the US airports (overall mean=532.5 vs 188.7 µg/m3), higher outside DSRs than in the US airports (overall mean=50.1 vs 43.7 µg/m3), and at comparable levels with the US airports in the terminals away from DSRs (overall mean=13.8 vs 11.5 µg/m3. Findings show that travellers and employees in or near DSRs in the airports assessed in Thailand are being exposed to even higher levels of SHS than in US airports that still have DSRs.

Conclusions

Extremely high levels of SHS in and adjacent to DSR show that these rooms are not providing safe air quality for employees and travellers. These high levels of exposure are above those levels reported in US airports and show the need for remedial action to ensure safe air quality in international airports in Thailand.

Regulations that reduce nicotine and eliminate menthol in cigarettes have been proposed to the US Food and Drug Administration (FDA) as product alterations that could reduce smoking prevalence in the USA. This study sought to assess the public response to either action.

Methods

A mail survey of a representative sample of 1074 adults was conducted in two major metropolitan areas to determine the level of support for immediate, gradual or no reduction of menthol and nicotine in cigarettes.

Results

There was more support for reducing nicotine (79%) than for reducing or removing menthol (59.5%). Most smokers (59.2%; 95% CI 50.7 to 67.2) and 36% of non-smokers (95% CI 31.7 to 40.8) opposed eliminating menthol, but few smokers (23.8%) or non-smokers (20.3%) were opposed to reducing nicotine. Logistic regression showed no significant effect of smoking status on support for reductions in nicotine, but that smokers were significantly less supportive than non-smokers of FDA action on menthol (OR=0.32, 95% CI 0.21 to 0.49). A significant race by smoking status interaction showed that African-American smokers were more supportive of removing menthol than non-African-American smokers.

Conclusions

The greater smoker support for reductions in nicotine than menthol could be due to inaccurate beliefs about the disease risk associated with the two substances (ie, a belief that nicotine is more harmful than menthol), or to greater awareness of the sensory role that menthol plays in smokers’ satisfaction. In any case, if FDA goes ahead with regulations to remove menthol, it will be important to develop strategies to reduce smoker resistance.

To determine whether snus might become a strategy for reducing the harm associated with cigarette smoking in the USA as appears to be the case in Sweden, we examined receptivity to snus use in two cities with the greatest exposure to the major brands.

Methods

A dual frame, telephone survey and a brief mail survey were conducted in 2011 and 2012 in Indianapolis, Indiana and Dallas/Fort Worth Texas. Over 5000 adults completed surveys. Trial, ever use, current use and reasons for using or quitting snus after trial were measured.

Results

Among male smokers, 29.9% had ever tried snus (CI 22.7 to 38.1) and 4.2% were current users (CI 1.6 to 10.7). Among female smokers, 8.5% ever tried snus (CI 4.4 to 15.7) and current use was unknown. Current use was virtually absent among former smokers and never smokers. A major predictor of any level of snus use was current use of conventional smokeless tobacco. Those who tried and gave up snus cited curiosity (41.3%) and the fact that it was available at low or no cost (30%) as reasons for trial; reasons for not continuing included preferring another form of tobacco (75.1%) and disliking the mouth feel (34.6%). Almost all current snus users indicated that they were trying to cut down on cigarettes, but few (3.9%) were using it to quit smoking entirely.

Conclusions

The low rate of adoption of snus suggests that neither the hopes nor the fears surrounding this new product are likely to be realised in the USA with the current marketing patterns.
